Description

Dual polarized cross dipole and antenna arrangement with two such dual polarized cross dipoles

The invention relates to a dual-polarized cross dipole and an antenna arrangement with two such dual-polarized cross dipoles.

Dipole radiators have become known, for example, from the prior publications DE 197 22 742 A and DE 196 27 015 A. Such dipole radiators can have a conventional dipole structure or consist, for example, of a crossed dipole or a dipole square, etc.

Such dipole radiators are usually fed so that a dipole or radiator half is DC-connected (ie galvanically) or capacitively or inductively (ie electromagnetically), whereas the inner conductor of a coaxial connecting cable with the second dipole or radiator half DC (ie again galvanic) or capacitive or inductive is connected. The feed takes place in each case at the mutually facing end portions of the dipole or radiator halves.

This is evident, for example, from DE 10 2015 007 504 A, which shows a dipole-shaped radiator arrangement. This includes four spaced-apart, non-overlapping dipole vanes spaced apart by a support from a reflector. The supply takes place via appropriate supply lines or printed circuit boards, the galvanic or capacitive to the respective Wings are coupled. These feed lines of different dipole radiators intersect.

Such a classic structure is also found in WO 2014/132254 AI again. The individual dipole wings are arranged spaced from one another without overlapping. About corresponding carrier they are also spaced from the reflector. Feeder lines such as cable or microstrip are led up from the reflector in the direction of the respective dipole wing along the carrier and cross over in the upper end region before they are galvanically soldered to the respective dipole wing.

The disadvantage here on the one hand, that a large number of components are needed. These are the individual carriers with the dipole wings and the feeders.

A disadvantage of the cross dipoles from the prior art is also that the manufacturing costs and the resulting costs are high. In addition, an increased weight is added, which means that they can not be automatically placed on a basic body in an SMD placement process.

It is therefore the object of the present invention to provide a dual polarized cross dipole, which can be constructed simpler and cheaper than the Kreuzdipo le previously known in the art, at least similar electrical properties to be achieved.

The object is achieved by the dual-polarized crossed dipole according to independent claim 1 and by an antenna arrangement comprising at least two such dual-polarized crossed dipoles according to claims 34 and 37. In claims 2 to 33 are advantageous developments of the dual-polarized cross dipole again, whereas the claims 35, 36, 38 and 39 include a development of the antenna arrangement. The dual-polarized cross dipole according to the invention comprises a first dipole radiator and a second dipole radiator. These are rotated by 90 ° so arranged to each other that the cross dipole in two perpendicular to each other sending and / or receiving polarization planes. The first and second dipole radiators each comprise two dipole halves. The first dipole half of the first dipole radiator comprises a ground terminal carrier and a dipole ground plane. A first end of the dipole wing is connected to a first end of the ground terminal carrier, wherein a second end of the ground terminal carrier is attachable to at least one base body and connectable to a reference ground. The second dipole half of the first dipole radiator comprises a signal terminal carrier and a dipole signal vane. The dipole signal vane is connected at its first end to a first end of the signal terminal carrier. The same applies to the first dipole half and the second dipole half of the second dipole radiator.

The signal terminal carrier of the first dipole radiator runs parallel or with a component predominantly parallel to the ground terminal carrier of the first dipole radiator. The same applies to the signal terminal carrier of the second dipole radiator. The dipole signal vane and the dipole mass vane of the first dipole radiator run in the opposite direction, in particular they extend in a top view offset by 180 ° to one another. The same applies to the dipole signal vane and the dipole mass vane of the second dipole radiator. The first dipole half of the first and second dipole radiators is preferably formed in one piece. The same applies to the second dipole half of the first and second dipole radiators.

The dipole signal wing of the second dipole radiator dips under the dipole signal wing of the first dipole radiator. Conversely, of course, the dipole mass vane of the second dipole radiator could also dip under the dipole mass vane of the first dipole radiator. It could also be that the dipole mass vane 5 of the first dipole radiator dives under the dipole signal vane of the second dipole radiator, or that the dipole signal vane of the second dipole radiator dips under the dipole mass vane of the first dipole radiator.

In other words, precisely exactly one wing of a dipole radiator emerges under exactly one wing of another dipole radiator. It is particularly advantageous on the dual-polarized crossed dipole that the respective dipole halves are formed in one piece. Thus, the corresponding dipole mass vane is integrally formed with its ground terminal carrier and the Dipolsignalflügel with its signal terminal carrier. As a result, the structure is greatly simplified because it is no longer necessary to raise and cross the signal line or ground line of a waveguide, which must be connected galvanically or capacitively to the dipole blades. The ground terminal carrier is preferably connected to a reference ground only at its second end, whereas the signal terminal carrier is preferably connected to and fed with a first and second high frequency line, respectively, at its second end (which is opposite the first end).

In particular, the dual polarized crossed dipole is formed from sheet metal parts, preferably having a thickness of less than 1mm, less than 0.9mm, 0.8mm, 0.7mm, 0.6mm, 0.5mm, but preferably more than 0.3mm , 0.5mm, 0.7mm. The first and / or second dipole half of both dipole radiators is preferably formed from a sheet metal stamping and / or sheet metal cutting part (eg laser cutting part). In particular, this is therefore in a sheet metal stamping and / or sheet cutting process, to which a laser cutting process belongs manufactured. The first and / or second dipole half of both dipole radiators is also preferably or additionally formed from a bent sheet metal and / or sheet metal part, that is produced in such a corresponding method. It would also be possible for each dipole half of both dipole radiators to be made in one piece from a flexible printed circuit board.

More preferably, the dual-polarized cross dipole can also be made from printed circuit boards or with a 3D printing process.

The dipole signal vane and / or the dipole mass vane of both dipole radiators lie with respect to their predominant length in a common plane or in different planes, wherein the common plane or the different planes are arranged parallel to each other and in particular parallel to at least one main body (eg reflector), on which the dual-polarized dipole is placed. In this case, the larger surface of the respective dipole signal vane or dipole mass vane runs parallel or with a component predominantly parallel to the at least one main body. In a preferred embodiment, the dipole signal vane and the dipole vane of the first and / or second dipole radiator are subdivided over their predominant length or over their entire length by a separating slot into two vane segments spaced apart from one another, wherein the vane segments, each spaced apart from one another, have different lengths are. This allows the two dipole radiators to transmit and receive in different frequency bands. A galvanic connection of the two wing segments takes place only at the first end, via which they are connected to the respective ground terminal carriers or signal terminal carriers.

In another embodiment of the cross dipole according to the invention, the dipole signal vane and / or the dipole mass vane of the first and / or second dipole radiator are subdivided into at least two segments which run parallel or with a component predominantly parallel to one another, wherein these segments are arranged in different planes and over at least one intermediate segment are connected to each other. This results in a stepped course, whereby the respective Dipolsignalflügel or the respective Dipolmasseflügel can be easily passed through each other.

The segments, which are each arranged closer to the first end of the signal terminal carrier or ground terminal carrier, can be arranged closer to the at least one base body compared to the first ends of the signal terminal carriers or ground terminal carriers, whereby the respective dipole signal vane or dipole ground vane has a U-shaped course at least in the region of this segment.

In a further exemplary embodiment of the crossed dipole, the ground terminal carriers of the first and second dipole radiators are connected to one another in an electrically conductive manner at their second end and formed in one piece as a whole. This means that the first dipole half of the first dipole radiator and the first dipole half of the second dipole radiator are formed from a common element, in particular a common sheet metal part. Preferably, the respective ground terminal carriers are connected to each other exclusively at their second end. Via a longitudinal slot, they are galvanically starting from their second end in the direction of their first end. separated from each other. In particular at its first end, the ground terminal carriers of both dipole radiators are preferably arranged at a distance from each other.

In another refinement of the crossed dipole, the ground terminal bar of the first and / or second dipole radiator has an opening at its second end, through which the corresponding signal terminal carrier, which runs parallel to the ground terminal carrier, is led with its second end, both the second End of the signal terminal carrier of the first and second dipole radiator and the second end of the ground terminal 10 carrier of the first and second dipole radiator on the same side of the at least one base body ends or can be arranged. This allows the dual-polarized cross dipole to be SMD-solderable, that is to say designed as an SMD component. The dual-polarized cross-dipole has a weight of more than 0.3 g, 0.5 g, 1 g, 2 g, 3 g, but preferably less than 2.9 g, 1.9 g, 0.9 g, or wei s niger than 0, 4g if it is designed for a frequency range of 3GHz to 4GHz and made of aluminum.

In this context, it is of course also possible that the dual-polarized cross dipole can be plugged onto the at least one base body. In this case, the second end of the signal terminal carrier of the first and second dipole radiator would protrude beyond the second end of the ground terminal carrier of the first and second dipole radiators, that is, the at least one base body would be enforceable by the second end of the respective signal terminal carrier.

25

In a further development of the crossed dipole, this comprises a first and a second holding device. The first and second holding device consists of or comprises a dielectric material and is arranged between the respective ground terminal carrier and the signal terminal carrier of the first and second dipole radiators. The first or second holding device comprises a plurality of holding means which are both in engagement with the ground terminal carrier and in engagement with the signal terminal carrier of the respective dipole radiator and thus prevent relative displacement of the ground terminal carrier and the signal terminal carrier.

35 The first and the second holding device can preferably be formed from a common element, that is to say in one piece, and are preferably produced in a plastic injection molding process. The antenna arrangement according to the invention comprises at least a first and preferably also a second dual-polarized crossed dipole. The antenna arrangement further comprises at least one base body, on which the first and the second dual-polarized crossed dipole are arranged. The at least one main body can be, for example, a printed circuit board and / or a reflector. The signal terminal carriers of the two cross dipoles are preferably connected together as follows. A second end of the signal terminal carrier of the first dipole radiator of the first dual polarized crossed dipole is galvanically connected via a first connection (radio frequency line) to a second end of the signal terminal carrier of the first dipole radiator of the second dual polarized cross dipole. Conversely, a second end of the signal terminal carrier of the second dipole radiator of the first dual-polarized crossed dipole is galvanically connected via a second connection (high-frequency line) to the second end of the signal terminal of the second dipole radiator second dual-polarized cross dipole. As a result, a first and a second radio-frequency signal can be very easily supplied to the respective signal terminal carriers via their second end. The first or high-frequency signal is preferably coupled in or out in the middle of the first connection and the second connection. Such an antenna arrangement may also comprise further such dual-polarized cross dipoles. The antenna arrangement can also be referred to as a mobile radio antenna. The antenna arrangement is preferably still surrounded by a housing which is permeable or has only a low attenuation for the first and second high-frequency signal.

The dual-polarized cross dipole is very broadband and can be used in frequencies from 100 MHz to 6 GHz or up to 10 GHz. Particularly good results are achieved at frequencies of approximately 2.6 GHz and 3.5 GHz.

In the following, different embodiments of the dual-polarized cross dipole 1 according to the invention will be described. FIG. 1A shows a three-dimensional view of a first exemplary embodiment of the dual-polarized crossed dipole 1 according to the invention. FIG. 1B shows a plan view of this first exemplary embodiment. The dual-polarized crossed dipole 1 comprises a first dipole radiator 2 and a second dipole radiator 3. The first dipole radiator 2 is shown, for example, in FIG. 4A and the second dipole radiator 3 in FIG. 4B. The first dipole radiator 2 comprises two dipole halves 2a, 2b. The second dipole radiator 3 also comprises two dipole halves 3a, 3b. The first dipole half 2a of the first dipole radiator 2 is shown for example in FIG. 2A. The second dipole half 2b of the first dipole radiator 2 is shown in FIG. 3B. The first dipole half 3a of the second dipole radiator 3 is shown in FIG. 2A, whereas the second dipole half 3b of the second dipole radiator 3 is shown in FIG. Rahlers 3 of Figure 3A can be seen. In FIG. 2B, the second dipole halves 2b, 3b of both dipole radiators 2, 3 are shown in each case.

The first dipole half 2a of the first dipole radiator 2 comprises a ground terminal carrier 4 and a dipole ground plane. A first end 5a of the dipole ground plane 5 is galvanically and mechanically connected to a first end 4a of the ground terminal carrier 4. A second end 4 b of the ground terminal carrier 4 can be arranged on at least one main body 15. This main body 15 is shown for example in Figures 4A and 4B.

The second dipole half 2b of the first dipole radiator 2 comprises a signal terminal carrier 6 having a first end 6a and an opposite second end 6b and a dipole signal vane 7, wherein a first end 7a of the dipole signal vane 7 connects galvanically and mechanically to the first end 6a of the signal terminal carrier 6 is. The first dipole half 3a of the second dipole radiator 3 comprises a ground terminal carrier 8 and a dipole mass vane 9. A first end 9a of the dipole ground vane 9 is galvanically and mechanically connected to a first end 8a of the ground terminal carrier 8. A second end 8 b of the ground terminal carrier 8 can be arranged or arranged on the at least one main body 15. The second dipole half 3b of the second dipole radiator 3 comprises a signal terminal carrier 10 having a first end 10a and an opposite second end 10b. The second dipole half 3b of the second dipole radiator 3 also comprises a dipole signal vane 11, wherein a first end 11a of the dipole signal vane 11 is galvanically and mechanically connected to the first end 10a of the signal terminal carrier 10.

The signal terminal carrier 6 of the first dipole radiator 2 runs parallel or with a component predominantly parallel to the ground terminal carrier 4 of the first dipole radiator 2. The signal terminal carrier 10 of the second dipole radiator 3 runs parallel or with a component predominantly parallel to the ground terminal carrier 8 of the second dipole radiator 3. The wording "with a component predominantly parallel "is to be understood that angles of less than 45 ° between the ground terminal supports 4, 8 and the respective signal terminal supports 6, 10 are included. However, the angle is preferably less than 40 °, more preferably less than 35 °, 30 °, 25 °, 20 °, 15 °, 10 °, 5 °. A distance between the ground terminal carriers 4, 8 and the respective signal terminal carriers 6, 10 is preferably chosen so that a waveguide and preferably a stripline is formed. When dimensioning, it must be considered whether there is air or dielectrics between the signal line and the ground line.

If the distance is designed as a microstrip line, the distance between the ground terminal carriers 4, 8 and the respective signal terminal carriers 6, 10 is less than 5 mm, 4 mm, 3 mm, 2 mm, 1 mm, 0.8 mm, 0.6 mm or 0 in the case of an air microstrip line. 2mm and more preferably greater than 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.1mm, 2.1mm, 3.1mm, 4.1mm or 5.1mm.

The dipole signal vane 7 and the dipole mass vane 5 of the first dipole radiator 2 extend in the opposite direction. This means that in plan view (FIG. 1B) an angle of approximately 180 ° is formed between the dipole signal vane 7 and the dipole ground vane 5 of the first dipole radiator 2. The wording "approximately" means that it also includes a deviation of less than 10 °, 8 °, 7 °, 5 °, 3 °, 1 ° thereof.

The same applies to the dipole signal vane 1 1 and the dipole mass vane 9 of the second dipole radiator 3, which also extend in the opposite direction. The first dipole half 2a of the first dipole radiator 2 is integrally formed, and the second dipole half 2b of the first dipole radiator 2 is also formed. With regard to FIG. 2A, this means that the dipole mass vane 5 of the first dipole radiator 2 and the ground terminal carrier 4 of the first dipole vane 2 are formed from a common (sheet metal) part. The same also applies with regard to FIGS. 2B and 3B for the dipole signal vane 7 of the first dipole radiator 2 and the signal terminal carrier 6 of the first dipole radiator 2. These are also formed in one piece and consist of a single (bleaching) part. The same is true for the first dipole half 3a of the second dipole radiator 3 and the second dipole half 3b of the second dipole radiator 3. The first dipole half 3a is shown for example in FIG. 2A. The ground connection carrier 8 of the second dipole radiator 3 and the Dipolmasseflügel 9 of the second dipole radiator 3 are integrally formed and consist solely of a common (sheet) part. With reference to FIGS. 2B and 3A, it is shown that also the signal terminal carrier 10 of the second dipole radiator 3 and dipole signal vane 1 1 of the second dipole radiator 3 are constructed in one piece and consist of a single common (sheet metal) part.

With regard to FIG. 1A and FIG. 2B, it is also shown that the dipole signal vane 1 1 of the second dipole radiator 3 passes without contact under the dipole signal vane 7 of the first dipole radiator 2, ie runs through it. The two Dipolsignalflügel 7, 1 1 are galvanically isolated from each other.

In principle, it could also be the case that the dipole mass vane 9 of the second dipole radiator 3 penetrates without contact under the dipole mass vane 5 of the first dipole radiator 2.

The first and / or second dipole half 2a, 2b of the first dipole radiator 2 is, as already explained, formed from a single (common) (sheet metal) part. In particular, the first and / or second dipole half 2a, 2b is formed from a sheet metal stamping and / or sheet metal cutting part. A sheet metal cutting part is to be understood as a metal sheet cut with a laser and / or a knife. A sheet consists of an electrically conductive metal or a metal alloy.

The first and / or second dipole half 2a, 2b of the first dipole radiator 2 can alternatively or additionally also be formed from a sheet-metal bending and / or sheet-metal edge part, so that a certain shape is achieved. The same also applies to the first and / or second dipole half 3a, 3b of the second dipole radiator 3.

It is also shown in FIGS. 2A and 2B that the first dipole halves 2a, 3a of both dipole radiators 2, 3 and the second dipole halves 2b, 3b of both dipole radiators 2, 3 altogether consist of exactly three metal parts which are constructed differently from each other, preferably at least two metal parts are made with the same tool. In FIG. 1B, the dipole signal vanes 7, 11 of both dipole radiators 2, 3 extend approximately at an angle of 90 ° to one another. The same also applies to the dipole mass wings 5, 9 of both dipole radiators 2, 3. The dipole mass vane 5 of the first dipole radiator 2 is also arranged offset at an angle of approximately 90 ° to the dipole signal vane 1 1 of the second dipole radiator 3. The wording "approximately" means that deviations of less than 5 °, 4 °, 3 °, 2 °, 1 ° from the 90 ° are considered to be included. The same also applies to the dipole mass vane 9 of the second dipole radiator 3. This likewise runs at an angle of approximately 90 ° to the dipole signal vane 7 of the first dipole radiator 2.

FIGS. 1A and 1B show the alignment of the dipole mass wings 5, 9 and the dipole signal wings 7, 11 of both dipole radiators 2, 3. These are not arranged edgewise to the at least one main body 15, but are elongated. The cross section through the dipole mass vane 5, 9 and through the dipole signal vane 7, 1 1 is rectangular. The longer sides of the rectangle run parallel or with a component predominantly parallel to at least one main body 15, whereas the shorter sides of the rectangle run perpendicular or with a component predominantly perpendicular to the at least one main body 15. This means that, in plan view of the dual-polarized crossed dipole 1 (FIG. 1B), the larger surface area of the dipole mass vane 5, 9 and the dipole signal vane 7, 11 is visible, compared to a side view of FIGS. 4A and 4B.

FIG. 1B also shows that the dipole mass wings 5, 9 of both dipole radiators 2, 3 are of equal length. It would also be possible that these are of different lengths. The same also applies to the dipole signal wings 7, 1 1 of both dipole radiators 2, 3. In the embodiment of Figure 1B, these are also the same length. However, they could also be different lengths. Upon closer examination, it should be noted that the dipole signal wings 7, 1 1 of both dipole radiators 2, 3 are the same length as the dipole mass vanes 5, 9 of the two dipole radiators 2, 3. It would also be conceivable here that at least one dipole signal vane 7, 1 1 or both dipole signal wings 7, 11 are longer or shorter than one or both dipole mass wings 5, 9. It is also conceivable that the dipole signal vane 7 and / or dipole mass vane 5 of the first dipole radiator 2 has a widening over a partial length. With regard to FIG. 1B, this is the case for the dipole signal vane 7 of the first dipole radiator 2, which is narrower at its first end 7a. Preferably, the dipole signal vane 7 and the dipole mass vane 5 of the first dipole radiator 2 are the same width over the greater length. The same also applies to the dipole signal vane 1 1 and the dipole mass vane 9 of the second dipole radiator 3. It can also be seen from FIG. 2A that the ground terminal carrier 4 of the first dipole radiator 2 and the ground terminal carrier 8 of the second dipole radiator 3 are electrically conductive at their second end 4b, 8b interconnected and formed in one piece. The first dipole halves 2a, 3a of both dipole radiators 2, 3 are therefore formed from a single (common) (sheet) part. At their second ends 4b, 8b, the two ground connection carriers 4, 8 comprise a support surface 13 or a pedestal. About this support surface 13 of the dual-polarized cross dipole 1 on the body 15 can be arranged. This support surface 13 may also have additional webs 13 a, which protrude outwardly to avoid tipping of the dual-polarized cross dipole 1 in particular when this is designed as an SMD component. However, such a bearing surface 13 is not absolutely necessary. The ground terminal carrier 4, 8 could also be inserted in the at least one base body 15. The ground terminal carrier 4 of the first dipole radiator 2 and the ground terminal carrier 8 of the second dipole radiator 3 are preferably connected to one another in an electrically conductive manner exclusively at their second end 4b, 8b. This means that the ground terminal carrier 4 of the first dipole radiator 2 and the ground terminal carrier 8 of the second dipole radiator 3 are galvanically separated from each other by a longitudinal slot 14 between their second ends 4b, 8b and the first ends 4a, 8a.

It can also be seen in FIG. 1A that the ground terminal carrier 4 of the first dipole radiator 2 is wider along its entire length than the signal terminal carrier 6 of the first dipole radiator 2. The same applies to the ground terminal carrier 8 of the second dipole radiator 3 with respect to the signal terminal carrier 10 of the second one Dipolestrahlers 3. Basically it would be synonymous it is possible for the ground terminal carriers 4, 8 of both dipole radiators 2, 3 to be wider at least along a partial length than the corresponding signal terminal carriers 6, 10. The at least one main body 15 comprises a printed circuit board and / or a reflector. In this case, the reflector could also be formed as a conductive layer on one side of the printed circuit board.

The at least one main body 15 could also be part of the dual polarized cross dipole 1.

In the dual polarized crossed dipole 1, the electrical phase center and the mechanical (eg, rotational / weight) center are offset from each other. This means that these centers enforce different regions of the dual-polarized cross dipole 1. In this case, the first dipole radiator 2 and the second dipole radiator 3 each have their own electrical phase center. Both electrical phase centers are offset from one another. Such a construction achieves very high insulation values of at least -20 dB, -30 dB, -40 dB at the base point of the crossed dipole 1. FIGS. 4A and 4B show various lateral (cut) representations of different dipole halves 2 a, 2 b and 3 a, 3 b of the cross dipole 1 according to the invention. The dipole mass vane 5 and the dipole signal vane 7 of the first dipole radiator 2 lie in a common plane over their entire length. This plane is aligned parallel or with a component predominantly parallel to the at least one main body 15. In principle, it would also be possible for the dipole mass vane 5 and the dipole signal vane 7 of the first dipole radiator 2 to lie in a common plane at least with the greatest part of their longitudinal extent. The same also applies to the dipole mass vane 9 and the dipole signal vane 1 1 of the second dipole radiator 3.

Preferably, the dipole signal vanes 7, 11 of both dipole radiators 2, 3 and / or the dipole mass vanes 5, 9 of both dipole radiators 2, 3 lie at least with the greatest part of their longitudinal extension or with the entire part of their longitudinal extent in the common plane or in at least two. different levels, which are arranged parallel to each other. Arrows in FIGS. 4A, 4B show the field distribution of the E field. This distribution is predominantly symmetrical and there is a high degree of symmetry, in particular during the transition of the E field between the respective ground terminal carriers 4, 8 of both dipole radiators 2, 3 and the respective signal terminal carriers 6, 10 of both dipole radiators 2, 3 to the respective dipole mass vane 5, 9 and the dipole signal wings 7, 1 1 of both dipole radiators 2, 3 before.

FIGS. 4A and 4B also show approximate dimensions of the dipole signal wings 7, 11 and of the dipole mass wings 5, 9 of both dipole radiators 2, 3. Furthermore, a height, ie a distance of the dipole signal wings 7, 11 or the dipole mass wings 5, 9 to the at least one main body 15 is also indicated. The length of the dipole signal vane 7 and of the dipole mass vane 5 of the first dipole radiator 2 is preferably 0.25λ, where λ is the center frequency of a first high-frequency signal which can be transmitted or received via the first dipole radiator 2. A deviation of + 0.15 λ is permissible. A distance between the dipole signal vane 7 and the dipole mass vane 5 and the at least one base body 15 is also preferably 0.25 λ, again permitting a deviation of + 0.15 λ.

The same also applies to the dipole signal vane 1 1 and the dipole mass vane 9 of the second dipole radiator 3. These likewise have a length which corresponds approximately to 0.25 λ, where λ in this case the center frequency of a second dipole radiator 2 can be emitted or. is receivable second high frequency signal. A distance between the dipole signal vane 1 1 and the dipole mass vane 9 of the second dipole radiator 3 and the at least one base body 15 is also approximately 0.25 λ. Here, too, a deviation of + 0.15 λ is permissible.

The center frequencies of the first and second high frequency signals may be the same or different. FIG. 4B likewise shows a curved course of the dipole signal vane 11 of the second dipole radiator 3. The Dipolsignalflügel 1 1 of the second dipole radiator 3 is divided into at least two segments I ii and 1 1 ₂ , the parallel or with a component predominantly parallel to each other. However, these segments 11, 12 are arranged in different planes (at different distances from the at least one main body 15). These segments I ii, 1 12 are interconnected galvanically and mechanically via an intermediate segment 1 1 ₃ . The first segment I ii is arranged closer to at least one main body 15 and thus closer to the second end 10 b of the signal terminal carrier 10 of the second dipole radiator 3 than the second segment 1 1 _second The first segment I 2 of the dipole signal vane 1 1 of the second dipole radiator 3, which also adjoins the first end 10 a of the signal terminal carrier 10 of the second dipole radiator 3, is also located closer to the second end 10 b of the signal terminal carrier 10 than the first end 10 a of FIG Signal connection carrier 10. As a result, the Dipolsignalflügel 1 1 over a partial length, in particular over the length of the first segment 1 11 a U-shaped course (falling and rising gradient) on.

As will be explained later, such a course would also be possible for the other dipole signal vane 7 of the first dipole radiator 2 and / or for the dipole mass vane 5, 9 of both dipole radiators 2, 3. FIGS. 4A and 4B also show that the second end 6b, 10b of both signal terminal carriers 6, 10 of the two dipole radiators 2, 3 projects beyond the second end 4b, 8b of the ground terminal carriers 4, 8 of both dipole radiators 2, 3. This makes it possible for the second end 6b, 10b of the signal terminal carriers 6, 10 of both dipole radiators 2, 3 to be introduced into a corresponding receiving opening of the at least one main body 15 or for the second ends 6b, 10b of both signal terminal carriers 6, 10 both Dipole radiator 2, 3 pass through the base body 15. In this case, feeding of the two signal terminal carriers 6, 10 of both dipole radiators 2, 3 would take place from the second side of the at least one main body 15, ie from the side opposite the upper side, ie the first side of the at least one main body 15 the (the upper side) the ground terminal supports 4, 8 are arranged or attached with their second ends 4b, 8b.

In principle, it would be possible that in each case an inner conductor of two coaxial cables with one of the second ends 6b, 10b of the two signal terminal carriers 6, 10 is electrically connected via a plug, screw and / or solder connection, whereas the respective outer conductor of the Koaxialka - when galvanically connected to the second ends 4b, 8b of the ground terminal carrier 4, 8 directly or indirectly via a further ground plane (eg on the at least one base body 15). In FIG. 2A, two openings 17, 18 are formed in the support surface 13 or the two second ends 4b, 8b of the ground connection carriers 4, 8 of both dipole radiators 2, 3. A first opening 17 is formed at the second end 4b of the ground terminal carrier 4 of the first dipole radiator 2. A second opening 18 is formed at the second end 8 b of the ground terminal carrier 8 of the second dipole radiator 3. With regard to FIGS. 4A and 4B, the second end 6b, 10b of the signal terminal carriers 6, 10 of the two dipole radiators 2, 3 pass through these openings 17, 18 in the second ends 4b, 8b of the two ground terminal carriers 4, 8. The signal terminal carriers 6, 10 of both dipole radiators 2, 3 are non-contact, ie, galvanically separated from the ground terminal carriers 4, 6 of both dipole radiators 2, 3.

In this context, reference is made to another embodiment in FIG. FIG. 10 shows that the dual-polarized crossed dipole 1 is designed as an SMD component. The first and second openings 17, 18 extend (also) laterally out on the ground terminal carrier 4, 8 of both dipole radiators 2, 3, so that the respective signal terminal carrier 6, 10 with its second end 6b, 10b passes through the corresponding opening 17 , 18 (bent), whereby both the second end 6b, 10b of the signal terminal carriers 6, 10 of both dipole radiators 2, 3 and the second end 4b, 8b of both ground terminal carriers 4, 8 of the two dipole radiators 2, 3 terminate in the same plane and in particular on the same side of the at least one base body 15 can be arranged.

The second ends 6b, 10b of the signal terminal carriers 6, 10 and the second ends 4b, 8b of both ground terminal carriers 4, 8 of the two dipole radiators 2, 3 are therefore SMD-solderable. Such a soldering process can be done in a reflow process.

FIG. 5 shows a second exemplary embodiment of the dual-polarized crossed dipole 1 according to the invention. The cross-dipole 1 shown there is constructed essentially as in the case of the first exemplary embodiment, to which reference is hereby made. In the following, only the smaller companies still lit up. Both dipole signal wings 7, 11 of both dipole radiators 2, 3 and both dipole mass wings 5, 9 of the two dipole radiators 2, 3 have an at least partially curved or step-shaped course. FIG. 6A shows a side (sectional) illustration of the first and second dipole halves 2a, 2b of the first dipole radiator 2, whereas FIG. 6B shows a lateral (sectional) illustration of the first and second dipole halves 3a, 3b of the second dipole radiator 3.

With regard to FIG. 6A, it is shown that the dipole signal vane 7 of the first dipole radiator _{2 is} subdivided into at least two segments 7i and 7 ₂ . Both segments 7i, 7 ₂ are parallel or with a component predominantly parallel to each other. These segments 7i, 7 ₂ are then arranged in different planes and connected via at least one intermediate segment 7 ₃ galvanically and mechanically. This results in the stepped course shown in FIG. 6A.

The same also applies to the dipole mass vane 5 of the first dipole radiator 2. This is likewise subdivided into two segments 5 _{l 5} 5 ₂ , which are arranged parallel or with a component predominantly parallel to one another. These segments 5 _{l 5} 5 ₂ run in different planes and are electrically and mechanically interconnected via at least one intermediate segment 5 ₃ . This also results in a step-shaped course.

The dipole signal vane 7 and the dipole mass vane 5 of the first dipole radiator 2 are constructed identically or approximately identically in this case. FIG. 5 shows that the first segment 7i of the dipole signal vane 7 has a smaller width than the first segment 5i of the dipole mass vane 5 of the first dipole radiator 2. This is because the dipole signal vane 7 of the first dipole radiator 2 is located above the dipole signal vane 11 of the second dipole radiator 3 runs and is avoided by the smaller width that these two Dipolsignal- wings 7, 1 1 galvanically contact each other or capacitive (strong) couple.

In principle, it would be possible for the first segments 7i or 5l _{5 of} the dipole signal vane 7 or of the dipole mass vane 5 to extend in the direction of the at least one base body 15, whereby in particular in the region of the first th segments 5 _{l 5} 1 _\ would reach a U-shaped course of the Dipolsignalflügels 7 or the Dipolmasseflügels 5 of the first dipole radiator. 2

Such a U-shaped course is shown in FIG. 6B for the dipole signal vane 11 and the dipole ground vane 9 of the second dipole radiator 3. As already described with respect to the dipole signal blade 11, in this exemplary embodiment the dipole mass vane 9 of the second dipole radiator 3 also comprises a U-shaped profile. The dipole mass vane 9 of the second dipole radiator 3 is likewise subdivided into at least two segments 9 ₁ , 9 ₂ , which run parallel or with a component predominantly parallel. These segments 9 _{l 5} 9 ₂ are arranged in different planes and connected to each other at least via an intermediate segment 9 ₃ . This would first result in a step-shaped course. However, after the first segment 9 _\ of the dipole mass wing 9 of the second dipole antenna element 3 which adjoins the first end 8a of the grounding terminal member 8 of the second dipole antenna 3, closer toward the second end 8b of the ground connection member 8, ie, closer in the direction of at least one Base body 15 is arranged as the first end 8a of the ground terminal carrier 8, first results in a falling and then by the connecting segment 9 again rising course of the dipole mass profile 9, so that it has a U-shaped course at least in the region of the first segment 9i.

In principle, the dipole signal vane 1 1 and the dipole mass vane 9 of the second dipole radiator could only have a step-shaped profile, wherein the term "step-shaped curve means that the first segment \ \ _\ or 9 _{\ of} the dipole signal vane 1 1 or of the dipole mass vane 9 are not arranged closer to the at least one main body 15 than the second end of the corresponding signal terminal carrier 10 or ground terminal carrier 8, so that in particular an ever increasing progression of the in the direction of the respective second end 1 lb or 9b of the dipole signal vane 1 or of the dipole mass wing 9 takes place.

FIG. 7 shows a third exemplary embodiment of the dual-polarized crossed dipole 1 according to the invention. FIGS. 8A and 8B show various side-by-side (cut) representations of different dipole halves 2 a, 2 b and 3 a, 3 b, respectively, of the dual-polarized crossed dipole 1. The dual polarized crossed dipole 1 of FIGS. 7, 8A, 8B is constructed substantially in accordance with the previous embodiments, to which reference is hereby made. FIG. 8B shows that the dipole signal vane 7 and the dipole mass vane 5 of the first dipole radiator 2 are constructed symmetrically with respect to one another. As a result, a high degree of symmetry is achieved in the transition of the electric field between the signal terminal carrier 6 and the ground terminal carrier 4 of the first dipole radiator 2 toward the dipole signal vane 7 and the dipole mass vane 5. The principal distribution of the E-field in the food area of the wings 5, 7 is shown by the arrows in FIG. 8B.

FIG. 8A shows that only the dipole signal vane 1 1 of the second dipole radiator 3 has a step-shaped profile. This means that the first end 10a of the signal terminal carrier 10 is arranged closer to the at least one main body 15 than the first end 8a of the ground terminal carrier 8 of the second dipole radiator 3. There is therefore a height offset between the first end 1 la of the dipole signal vane 11 and This height offset leads to a slightly asymmetric E field distribution but still to almost identical S parameters and a nearly identical far field compared with the cross dipole of Figure 4B in which a symmetrical widening of the microstrip line (signal terminal carrier 10 or ground terminal carrier 8) takes place.

FIG. 13A shows some electrical properties of the first three exemplary embodiments of the dual-polarized crossed dipole 1 according to the invention. The first embodiment (V001) is shown in Figs. 1A to 4B, whereas the second embodiment (V002) is shown in Figs. 5 to 6B, and the third embodiment (V003) is shown in Figs. 7 to 8B. FIG. 13A shows electrical values representing the electrical isolation of the two dipole radiators 2, 3 relative to one another for each of the three exemplary embodiments in a frequency range from 3 GHz to 4 GHz. The first embodiment (V001) is shown with a solid line, whereas the second embodiment (V002) is shown with a broken line and the third embodiment (V003) is shown with a dotted line. In addition to the Frequency, the S-parameters are plotted, wherein the second end 6b or 10b of a signal terminal carrier 6 or 10 fed and the second end 10b or 6b of the other signal terminal carrier 10 or 6 is measured with respect to the signal level. Although the third embodiment (V003) has the lowest insulation strength between the individual dipole radiators 2, 3, it has the most constant profile. The highest insulation strength is achieved in the first embodiment (V001), with the second embodiment (V002) being more suitable for lower frequencies. The first embodiment (V001) also shows the widest-band fit because it has the most compact curve in the Smith chart. See FIG. 13B. Since later preferably two cross dipoles 1 are connected together, the impedance curve in the Smith diagram should ideally be very compact on the real axis at about 100 ohms. Overall, it can be seen that a symmetrical construction of the individual dipole mass wings 5, 9 with respect to the respective oppositely extending dipole signal vanes 7, 11 is desirable, and that, in particular, the U-shaped profile gives good results. In the case of the U-shaped profile, it is ensured that the first ends 4a, 6a or 8a, 10a of the mutually parallel ground terminal carriers 4, 8 and the signal terminal carriers 6, 10 end approximately at the same height (above the at least one main body 15). From this common height, only then does a dipole signal vane 1 1 begin to diverge under the other dipole signal vane 7.

FIG. 9 shows a three-dimensional view of a fourth exemplary embodiment of the dual-polarized crossed dipole 1 according to the invention.

The dipole mass vane 5 and the dipole signal vane 7 of the first dipole radiator 2 are subdivided over the greatest part of their longitudinal extent or along their entire length by a separating slot 20 into two wing segments 5 ', 5 "and 7', 7" spaced apart from one another. These wing segments 5 ', 5 "and 7', 7" are spaced apart, so galvanically separated from each other. The wing segments 5 ', 5 "of the dipole mass profile wing 5 are preferably of different lengths. The same also applies to the wing segments 7', 7" of the dipole signal vane 7 of the first dipole radiator 2.

Preferably, the same also applies to the second dipole radiator 3. The dipole mass vane 9 and the dipole signal vane 1 1 of the second dipole radiator 3 are on the largest part of their longitudinal extent or along their entire length also by a separating slot 20 in each case two spaced-apart wing segments 9 ', 9 "or 1 Γ, 1 1" articulated. These wing segments 9 ', 9 "or 1 Γ, 1 1" are spaced apart, so galvanically separated from each other and are preferably of different lengths. The wing segments 9 ', 9 "of the dipole mass wing 9 of the second dipole radiator 3 have a different length and the wing segments 1 Γ, 1 1" of the Dipolsignalflügels 1 1 of the second dipole radiator 3 are preferably also different lengths.

By a similar length of the wing segments 5 ', 5 ", 7', 7", 9 ', 9 ", 1 Γ, 1 1", for example, the resonant frequency range of the crossed dipole 1 can be increased. By a different length of the wing segments 5 ', 5 ", 7', 7", 9 ', 9 ", 1 Γ, 1 1", for example, at least one further resonant frequency range can be generated. Wherein, as the resonant frequency range of a crossed dipole 1, a coherent region with a return loss of better than 6 dB and preferably better 10 dB and more preferably better 14 dB is preferably defined. In addition, it is conceivable that the wing segments 5 ', 5 "of the dipole mass vane 5 and / or the wing segments 7', 7" of the Dipolsignalflügels 7 of the first dipole radiator 2 over a portion of their length or over their vast length not parallel to each other, but in a Angle greater than 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 ° or 80 °. The same can also apply to the wing segments 9 ', 9 "of the dipole mass wing 9 and / or to the wing segments 1 Γ, 1 1" of the dipole signal wing 1 1 of the second dipole radiator 3. In particular, the wing segments 5 ', 5 ", 7', 7", 9 ', 9 ", 1 Γ, 1 1" can thus also form a square dipole and / or ultra-wideband (UWB) dipole. It has also been found that even a simple cross-dipole 1, as described in previous sections and figures, can exhibit dual band behavior or multiband behavior. By the interaction of maximum dipole extent orthogonal to the main body 15 (height of the dipole) and length of the waveguide between the ground terminal supports 4, 8 and the respective Signalanschlussträgern 6, 10 and maximum dipole expansion parallel to the main body 15 (length of the wing segments 5, 7, 9 , 1 1), a resonance frequency range of the cross dipole 1 can be extended and / or it At least two resonant frequency ranges can be generated. The height of the crossed dipole 1 and / or the length of the waveguide, which can be changed, for example, by meandering curves, thus likewise plays an essential role.

In addition, it has been found that the configuration of the wing segments 5 ', 5 ", 7', 7", 9 ', 9 ", 1 Γ, 1 1" can be arbitrary and these can be adapted to electrical requirements and manufacturing processes. The individual wing segments 5 ', 5 "of the dipole mass vane 5 of the first dipole radiator 2 are preferably only galvanically connected to one another at the first end 5a of the dipole mass vane 5 and are mechanically arranged on the ground terminal carrier 4 of the first dipole radiator 2. The same also applies to the wing segments 7', 7 These are also preferably only at the first end 7a of the Dipolsignalflügels 7 of the first dipole radiator 2 galvanically connected to each other and arranged in particular at the first end 6a of the Signalanschlussträgers 6 of the first dipole radiator 2. The same applies likewise to the second dipole radiator 3.

In principle, it is possible for the dipole signal vane 7 or the dipole mass vane 5 of the first dipole radiator 2 to have a curved section at its open second ends 7b or 5b, which are arranged opposite the first ends 7a and 5a, respectively. This section is bent away from the second end 4b of the mass connection carrier 4 and preferably extends away from the at least one main body 15 (upward). The height of the dual-polarized cross dipole 1 thereby increases. In FIG. 9, the bent section is arranged on one of the two wing segments 5 ', 5 "or 7', 7", so that the wing segments 5 ', 5 "or 7', 7" are of different lengths.

Such a bent portion may also be present in the second dipole radiator 3. The angle between the bent portion and the remaining, in particular parallel to the at least one base body 15 extending region of the Dipolsignalflügels 7 and Dipolmasseflügels 5 of the first Dipole radiator 2 is preferably greater than 90 ° and less than 180 °. The angle is preferably greater than 100 °, 1 10 °, 120 °, 130 °, 140 °, 150 ° 160 °, 170 ° and more preferably less than 165 °, 155 °, 145 °, 135 °, 125 °, 15 °, 105 ° or 95 °.

The angle is the smallest angle between the bent portion and the remaining part of the dipole signal vane 7 or the dipole mass vane 5 of the first dipole radiator 2. The same applies to the second dipole radiator 3.

FIG. 9 also shows that the webs 13a of the support surface 13 are bent downwards, that is to say in the direction of the at least one main body 15. These webs 13a can also engage in an opening of the at least one main body 15 or even enforce this, as has already been described with regard to the second ends 6b and 10b of the signal terminal carrier 6 and 10 respectively.

FIG. 9 also shows a first and a second holding device 25, 26. Both holding devices 25, 26 will be described in more detail with respect to the figures I IA, I IB and 12. They both consist of a dielectric material. The first holding device 25 is arranged between the ground terminal carrier 4 of the first dipole radiator 2 and the signal terminal carrier 6 of the first dipole radiator 2. The first holding device 25 comprises a plurality of holding means 25a, 25b, 25c, 25d which are both in engagement with the ground terminal carrier 4 of the first dipole radiator 2 and in engagement with the signal terminal carrier 6 of the first dipole radiator 2 and a displacement of the ground terminal carrier 4 and of the signal terminal carrier 6 relative to each other. The same also applies to the second holding device 26. This also includes a plurality of holding means 26a, 26b, 26c and 26d. The second holding device 26 is arranged between the ground terminal carrier 8 of the second dipole radiator 3 and the signal terminal carrier 10 of the second dipole radiator 3. In principle, it would also be possible that both holding devices 25, 26 are formed from a single, ie common (plastic injection molded) part. FIG. 12 shows that the first holding device 25 comprises a central body 27 which has a front and a rear side. At this front and back in each case a holding means 25a, 25b arranged in the form of a locking pin. The locking pins project away from the central body 27 and in each case penetrate into an opening in the ground terminal carrier 4 and in the signal terminal carrier 6 of the first dipole radiator 2, whereby displacement along a longitudinal axis passing through the dual-polarized crossed dipole 1 is prevented. These locking bolts may also comprise a locking means, so that removal of the ground terminal carrier 4 and the signal terminal carrier 6 is difficult or prevented.

At the front and rear are also other holding means 25 C, 25 D arranged in the form of Arretierungsfingern, which protrude from the central body 27 in the direction of the ground terminal carrier 4 and the Signalanschlusenträgers 6. These locking fingers engage behind both the ground terminal carrier 4 of the first dipole radiator 2 and the signal terminal carrier 6 of the first dipole radiator 2, whereby an increase in the distance between the ground terminal carrier 4 and the signal terminal carrier 6 is prevented. The locking fingers are preferably at least partially resilient.

The same situation applies to the second holding device 26, which also has a central body 28. Here, too, there are holding means 26a, 26b in the form of a locking pin and a plurality of holding means 26c, 26d in the form of locking fingers, which serve for fastening the ground terminal carrier 8 to the signal terminal carrier 10 of the second dipole radiator 3. The structure of the second holding device 26 corresponds to that of the first holding device 25. FIGS. 15A to 15C show further exemplary embodiments of the inventive crossed dipole 1, which are based on the fourth exemplary embodiment of the crossed dipole 1 according to FIG.

In FIG. 15A, the dipole mass vane 5 and the dipole signal vane 7 of the first dipole radiator 2 are in the greatest part of their longitudinal extent or along their entire length through a separating slot 20 in two spaced-apart vane segments 5 ', 5 "and 7', 7" respectively. divided. These flights gel segments 5 ', 5 "and 7, 7" are spaced, so galvanically separated from each other. The same applies to the wing segments 7, 7 "of the dipole signal vane 7 of the first dipole radiator 2. The same applies to the wing segments 9 ', 9" of the dipole mass vane 9 and for the wing segments 5', 9 " the wing segments 1 Γ, 1 1 "of the Dipolsignalflügels 1 1 of the second dipole radiator. 3

The wing segments 5 ', 9' of both dipole mass wings 5, 9 of the dipole radiators 2, 3 are inclined at their open ends 5b, 9b, whereby the total height of the cross dipole 1 increases. The inclination takes place preferably further away from the support surface 13 of the Kreuzdipols 1 (increasing inclination). The inclination could also run in the direction of the support surface 13 of the cross dipole 1 (sloping inclination), ie in the direction of a reflector or base body 15, not shown. The inclination is approximately 90 ° in FIG. 15A. A deviation of less than 40 °, 30 °, 20 °, 15 °, 10 ° 5 ° from the 90 ° is also possible. The same also applies to the wing segments 7 and 1 Γ of the dipole signal wings 7 and 1 1 of both dipole radiators 2, 3.

In FIGS. 15B and 15C, the at least one wing segment 5 ', 5 ", 7, 7" or all wing segments 5', 5 ", 7, 7" of the dipole mass vane 5 and / or the dipole signal vane 7 of the first dipole radiator 2 in FIG at least two sections arranged at an angle to each other, wherein the sections are preferably in each case in a common plane. 15B and 15C, the individual sections of the wing segments 5 ', 5 "extend parallel to one another, the same also applies to the sections of the wing segments 7, 7". The same also applies to the wing segments 9 ', 9 ", 1 Γ, 1 1" of the dipole mass vane 9 and the dipole signal vane 1 1 of the second dipole radiator 3. The individual wing segments 5', 5 ", 7, 7" of the dipole mass vane 5 and the Dipolsignalflügels 7 of the first dipole radiator 2 can have completely different lengths. The same also applies to the wing segments 9 ', 9 ", 1 Γ, 1 1" of the dipole mass vane 9 and the dipole signal vane 1 1 of the second dipole radiator 3.

The cross-sectional shape of at least one vane segment 5 ', 5 ", 7, 7" of the dipole mass vane 5 and / or the dipole signal vane 7 of the first dipole radiator 2 is constant over the length of the wing segment 5 ', 5 ", 7', 7". It could change too. The same also applies to the wing segments 9 ', 9 ", 1 Γ, 1 1" of the dipole mass vane 9 and the dipole signal vane 1 1 of the second dipole radiator 3. A further embodiment of the cross dipole 1 is shown in FIGS. 15D, 15E, 15F. The vane segments 5 ', 5 "of the dipole mass vane 5 of the first dipole radiator 2 diverge at an angle of, in particular, 90 ° (and less than + -10 ° or + -5 °.) The same applies to the vane segments 7', 7" of FIG The same situation applies to the wing segments 9 ', 9 "of the Dipolmasseflü- gel 9 of the second dipole radiator 3 and for the wing segments 1 Γ, 1 1" of the Dipolsignalflügels 1 1 of the second dipole radiator third

FIGS. 16A to 16C show a further exemplary embodiment of the cross-sectional pole 1. Here too, the dipole mass wings 5, 9 of both dipole radiators 2, 3 each again comprise two wing segments 5 ', 5 ", 9', 9". The same also applies to the dipole signal wings 7, 1 1 of both dipole radiators 2, 3. In this embodiment, however, there are still connecting portions 40. These electrically connect the open ends 7b of the wing segments 7 ', 7 "of the Dipolsig- nalflügels 7 of the first dipole radiator second The same also applies to the wing segments 1 Γ, 1 1 "of the Dipolsignalflügels 1 1 of the second dipole radiator 3. Optionally, the connecting portions 40 via at least one wing segment 7 ', 7", 1 Γ, 1 1 "still over, as for example is shown in Figure 16A. The term "galvanically connecting" can also be understood as short-circuiting.

Alternatively or additionally, this may also apply to the wing segments 5 ', 5 "of the dipole mass vane 5 of the first dipole radiator 2 and the wing segments 9', 9" of the dipole mass vane 9 of the second dipole radiator 3.

It is also shown that the open end 5b of the wing segment 5 'of the dipole mass vane 5 of the first dipole radiator 2 comprises an L-shaped extension, this L-shaped extension being arranged in the same plane as the major part of the vane segment 5' of the dipole mass vane 5. The same also applies to the open end 9b of the wing segment 9 'of the dipole mass vane 9 of the second dipole radiator 3. It could also be used for the open end 7b of the vane segment 7' of the dipole signal vane 7 of the first dipole radiator. lers 2 and for the open end 1 lb of the wing segment 1 Γ of the Dipolsignalflügels 1 1 of the second dipole radiator 1 1 apply. Instead of an L-shaped extension, a T-shaped extension or in particular a conical widening in the direction of the open end 5b, 9b, 7b, 11b would also be conceivable.

In figure 16C is also shown that a first segment 9 _\ of a blade segment 9 'of the Dipolmasseflügels 9 of the second dipole antenna element 3, which Toggle closes to the first end 8a of the grounding terminal member 8 of the second dipole antenna element 3 remote to the second end 8b of the ground terminal carrier 8 is arranged as the first end 8a of the ground terminal carrier 8, whereby the dipole mass vane 9 of the second dipole radiator 3 over a partial length has a, in the direction of a reflector, not shown, open U-shaped profile. The same also applies to the second wing segment 9 ", which, of course, can also apply to the dipole mass wing 9 itself if it is not divided into two wing segments 9 ', 9". The same can also apply to the dipole mass vane 5 of the first dipole radiator 2 and / or the dipole signal vane 7 of the first dipole radiator 2. This may also apply to the dipole signal vane 1 1 of the second dipole radiator 3.

In FIGS. 16A to 16C, the dipole mass vane 9 of the second dipole radiator 3 dips under the dipole mass vane 5 of the first dipole radiator 2. In this case, the ground terminal carriers 4, 8 of both dipole radiators 2, 3 are arranged closer to the center of the crossed dipole 1 than the two signal terminal carriers 6, 10. If the dipole ground vanes 5, 9 cross over, this has the advantage that the second dipole halves 2 b, 3b of both dipole radiators 2, 3 can be mounted more easily because they are only attached from the outside to the respective holding device 25, 26 attached (eg clipped or clicked).

In FIG. 17A, it is shown that the dipole signal vane 7 and the dipole mass vane 5 of the first dipole radiator 2 are T-shaped at their open second ends 7b, 5b. The second ends 7b, 5b are disposed opposite from their first ends 7a, 5a, which are connected to the signal terminal carrier 6 and the ground terminal support 4 of the first dipole radiator 2. Instead of a T-shaped design, these could also be L-shaped. to be. The same can also apply to the dipole signal vane 1 1 and the dipole mass vane 9 of the second dipole radiator 3.

FIG. 17B shows that the dipole signal vane 7 and the dipole ground plane 5 of the first dipole radiator 2 have a widening at their open second ends 7b, 5b. This broadening is triangular or conical in plan view. The second ends 7b, 5b are preferably more than twice as wide as the first ends 7a, 5a. The broadening preferably runs over less than 60%, 50%, 40%, 30%, 20% of the length of the dipole signal wing 7 and the dipole mass vane 5 of the first dipole radiator 2. The broadening is linear or stepped. The same can also apply to the dipole signal vane 1 1 and the dipole mass vane 9 of the second dipole radiator 3. In the cross-dipole 1 of Figures 16A and 16B, a higher bandwidth can be obtained with the same dimension as compared to a crossed dipole 1 whose second ends 5b, 7b, 9b, 11b are unchanged (e.g., Figure 1A). If the bandwidth is to be the same, a more compact design is possible in the case of the crossed dipole 1 of FIGS. 16A and 16B.

FIG. 19A shows that the dipole mass vane 9 of the second dipole radiator 3 dips under the dipole mass vane 5 of the first dipole radiator 2. In this case, the ground terminal carriers 4, 8 of both dipole radiators 2, 3 are arranged closer to the center of the crossed dipole 1 than the two signal terminal carriers 6, 10. If the dipole ground vanes 5, 9 cross over, this has the advantage that the second dipole halves 2 b, 3b of both dipole radiators 2, 3 can be mounted more easily because they are only attached from the outside to the respective holding device 25, 26 attached (eg clipped or clicked). The signal terminal carriers 6, 10 have a different width, so that the holding devices 25, 26, which do not engage (re-clip) the signal terminal carriers 6, 10 in a thinner area (thinner width) with their holding means 25c, 25d, 26c, 26d Direction of a thicker area (thicker range) can slip. FIG. 19B again shows how the dipole mass vane 9 of the second dipole radiator 3 passes under the dipole mass vane 5 of the first dipole radiator 2 surfaced. FIG. 19B shows the first dipole halves 2a, 3a of both dipole radiators 2, 3, which consist of a common metal part.

FIG. 19C shows a construction of the second dipole halves 2b, 3b of both dipole converters 2, 3. These are of identical construction (same dimensions), so that production is simplified.

For the cruciform dipole 1 of FIGS. 19A, 19B, 19C, mounting is simpler because only two different metal parts are necessary. A first metal part comprises the first dipole halves 2a, 3a of both dipole radiators 2, 3 and a second metal part each comprises a second dipole half 2b, 3b of a dipole radiator 2, 3. The assembly is also easier because two identical metal parts (second dipole halves 2b, 3b ) are clicked from the outside onto the integrally formed first dipole halves 2a, 3a. A likelihood of confusion does not exist here.

FIGS. 20A to 20C show a fifth exemplary embodiment of the inventive crossed dipole 1. According to FIG. 20C, the signal terminal carrier 6 of the first dipole radiator 2 and the signal terminal carrier 10 of the second dipole radiator 3 are electrically conductively connected or short-circuited at their first end 6a, 10a and are in one piece educated. As a result, the assembly is facilitated because fewer items are necessary. However, the electrical values are worse. In particular, the insulation values at the feed point, ie at the second ends 6b, 10b of the signal terminal carriers 6, 10, are worse (> 10 dB,> 15 dB and <20 dB). However, the

Insulation values are usually sufficient for applications such as massive MIMO and / or Small Cell and / or Automotive.

In this case, the first dipole halves 2a, 3a and the second dipole halves 2b, 3b consist exactly of a metal part.

Dipping from a dipole signal vane 7, 11 or a dipole mass vane 5, 9 of the first or second dipole radiator 2, 3 under another dipole signal vane 7, 11 or a dipole mass vane 5, 9 does not take place here. FIG. 20B shows that the first dipole halves 2a, 3a of both dipole radiators 2, 3 with their ground terminal carriers 4, 8 in the region of the second ends 4b, 8b of the ground terminal carriers 4, 8 have an L-shape or a C-shape in cross section or two below one Includes angle tapered segments. There is no stand 13 here. The ground terminal carriers 4, 8 are preferably plugged into a base body in the region of the second ends 4b, 8b.

In FIG. 20A, at least one holding device 25 is shown which comprises or consists of a dielectric material. The at least one holding device 25 is designed as a slide holder comprising a central body which is penetrated by a plurality of receiving slots, wherein the ground terminal support 4, 8 and the Signalanschlussträger 6, 10 in these receiving slots starting with their second ends 6b, 10b, 4b, 8b can be inserted or inserted. The sliding holder is at least along a partial length along the ground terminal support 4, 8 and the signal terminal carrier 6, 10 displaced. The at least one holding device 25 could alternatively also be designed as an injection-molded part, which is formed by overmolding of the ground terminal carriers 4, 8 and the signal terminal carriers 6, 10 with a plastic.

FIGS. 21A to 21C show a further exemplary embodiment of the cross dipole 1 according to the invention. In this exemplary embodiment, the dipole mass vane 5 of the first dipole radiator 2 dips under the dipole signal vane 1 1 of the second dipole radiator 3. In this case, the dipole mass wings 5, 9 of both dipole radiators 2, 3 are at different distances from the center of the

Cross dipole 1 arranged away. The same applies to the dipole signal wings 7, 11 of both dipole radiators 2, 3. The signal terminal carriers 6, 10 of both dipole radiators 2, 3 are on different sides (once on the outside and once on the inside) on the respective ground terminal carrier 4, 8 the dipole radiator 2, 3 attached.

FIG. 21C shows that the second dipole halves 2b, 3b of both dipole radiators 2, 3 are constructed identically or nearly identically to one another. The two second dipole halves 2b, 3b of both dipole radiators 2, 3 can be manufactured in particular with the same tool and in the same manufacturing process, whereby a cost-effective production is possible. The first dipole halves 2a, 3a of both dipole radiators 2, 3 are once again in one piece (FIG. 21B) and in particular consist of exactly one first metal part. The dual-polarized crossed dipole 1 also comprises exactly two second metal parts, which are preferably constructed identically to one another, wherein each of the second dipole halves 2b, 3b of both dipole radiators 2, 3 is formed from such a second metal part. In this case, there is the cross dipole

1 only from (exactly) two different metal parts. It would also be possible that it consists of (exactly) three different metal parts. This would apply if the second dipole halves 2b, 3b of both dipole radiators 2, 3 consisted of different metal parts.

The cross dipole 1 may comprise any of the shown holding devices 25 (click holders, slide holders, overmolding, etc.). In this connection, it is also mentioned that the dipole signal vane 1 1 of the second dipole radiator 3 could also dip below the dipole mass vane 5 of the first dipole radiator 2.

FIG. 14 shows a three-dimensional representation of the antenna arrangement 30 according to the invention, which has at least two dual-polarized crossed dipoles 1 a, 1 b.

In principle, the antenna arrangement 1 could also have only one dual polarized crossed dipole 1.

In this case, the antenna arrangement 30 comprises at least one main body 15. The first and at least one second dual-polarized cross dipole 1a, 1b are arranged on this at least one main body 15. A second end 6b of the signal terminal carrier 6 of the first dipole radiator 2 of the first dual-polarized crossed dipole la is galvanically connected via a first connection 31 to a second end 6b of the signal terminal carrier 6 of the first dipole radiator

2 of the second dual-polarized cross dipole lb. Conversely, a second end 10b of the signal terminal carrier 10 of the first dipole radiator 2 of the first dual-polarized crossed dipole la galvanic over a second connection 32 with a second end 10b of the signal terminal carrier 10 of the second dipole radiator 3 of the second dual-polarized cross dipole lb is galvanically connected. Both connections 32 are electrically isolated.

In this case, a first high-frequency signal can be coupled in or out in the first connection 31, whereas a second high-frequency signal can be coupled in or out in the second connection 32.

The second end 4b of the ground terminal carrier 4 of the first dipole radiator 2 of the first and second dual-polarized crossed dipole la, lb is galvanically or capacitively or inductively connected to a signal ground of the first high frequency signal and / or to a ground of the at least one base body 15. Conversely, the second end 8b of the ground terminal carrier 8 of the second dipole radiator 3 of the first and second dual-polarized crossed dipole la, lb is galvanically or capacitively or inductively connected to a signal ground of the second high-frequency signal and / or to a ground of the at least one base body 15 ,

The coupling of the first and / or second high-frequency signal preferably takes place in the middle of the first connection 31 or the second connection 32.

FIGS. 22A, 22B and 22C describe a further exemplary embodiment of the antenna arrangement 30 according to the invention, which has at least two dual-polarized cross dipoles 1a, 1b.

The signal terminal carrier 6 of the first dipole radiator 2 of the first dual-polarized cross dipole 1, 1a and the signal terminal carrier 6 of the first dipole radiator 2 of the second dual-polarized cross dipole 1, 1b are, together with their first connection 31, in one piece of a common bending and / or punching - And / or laser and / or Kant part formed. They are a single body.

The same applies to the signal terminal carrier 10 of the second dipole radiator 3. The signal terminal carrier 10 of the second dipole radiator 3 of the first dual-polarized cross dipole 1, 1a and the signal terminal carrier 10 of the second dipole radiator 3 of the second dual-polarized cross dipole 1, lb are together with their second Compound 32 in one piece from a common Bending and / or punching and / or laser and / or Kant part formed. They are a single body.

The power supply takes place as already described.

The ground terminal carriers 4, 8 of both dipole radiators 2, 3 of the first dual-polarized cross dipole 1, 1a and the ground terminal carriers 4, 8 of both dipole radiators 2, 3 of the second dual-polarized cross dipole 1, 1b are electrically connected to one another via a third connection 33 and together third compound 33 integrally formed from a common bending and / or punching and / or laser and / or Kant part. They are a single body.

In the following, the most important points of the dual-polarized cross-dipole 1 are shown briefly again. The supply of the respective signal terminal carrier 6 and 10 takes place exclusively at their second end 6b and 10b. Also, the ground connection to the ground terminal support 4 and 8 takes place exclusively at the second end 4b, 8b. The term "end" is understood to mean a length of less than 30% or 20% or 10% or 5% of the total length.

The dual-polarized cross dipole 1 is cable-free. This means that there are no connecting cables from the second ends 4b, 6b, 8b, 10b of the ground terminal carriers 4 and 8 or the signal terminal carriers 6 and 10 in the direction of the respective dipole signal vane 7 or 11 or in the direction of the dipole mass vane 5 or 9 extend.

The dual-polarized crossed dipole 1 is also free of any additional soldered electrical connectors (eg additional connecting plates), the different parts of a dipole half 2a, 2b and 3a, 3b electrically conductive with other parts of another or the same dipole half 2a, 2b and 3a, 3b interconnect. Each dipole half 2a, 2b or 3a, 3b is formed in one piece. In principle, the first dipole halves 2a and 3a of the first and second dipole radiators 2, 3 can be formed together from a one-piece (sheet metal) part. Under a one-piece training are just not to understand two different elements that are joined together by means of a solder joint. These features greatly simplify the design. The dual-polarized cross dipole 1 is designed in particular without solder joints. The single solder joints are used to connect the second ends 4b, 8b and 6b, 10b to the corresponding signal or reference ground or to the corresponding first or second high-frequency signal.

Such a construction achieves very high insulation values of at least -20 dB, -30 dB, -40 dB at the base point (base 13) of the crossed dipole 1. In group arrangements, moreover, further degrees of freedom are enabled in the decoupling between different dipole radiators 2, 3, since the electrical phase center and the mechanical center run through different regions. The dual-polarized cross dipole 1 can have a plan view dimensions of A / 2 x A / 2, whereas a distance between the Dipolsignalflügeln 7, 1 1 and the Dipolmasseflügeln 5 and 9 relative to the at least one main body 15 is approximately A / 4 , The wording "about" is to be understood as including deviations of preferably less than +/- 25%, 10%, 5%. The at least one main body 15 has, for example, a size of A x A. As A is preferably referred to the center frequency, in which the cross dipole 1 is operated. In FIG. 18A, it is shown that the crossed dipole 1 is made up of printed circuit boards 50, 51, 52. The ground terminal carrier 4 of the first dipole radiator 2 and the signal terminal carrier 6 of the first dipole radiator 2 can also be formed as conductor tracks 50 a, on different, opposite sides of a first printed circuit board 50. In particular, the conductor tracks 50a are copper surfaces which are arranged on a dielectric and are separated from one another by the dielectric.

The ground terminal carrier 8 of the second dipole radiator 3 and the signal terminal carrier 10 of the second dipole radiator 3 can also be formed as conductor tracks 51 a, on different, opposite sides of a second printed circuit board 51. The dipole mass vane 5 and the dipole signal vane 7 of the first dipole radiator 2 may be formed as conductor tracks 52a, 52b on a first side 52 'of a third printed circuit board 52. In this embodiment, the dipole mass vane 9 and the dipole signal vane 1 1 of the second dipole radiator 3 5 are formed as conductor tracks 52 c, 52 d on the first side 52 'of the third printed circuit board 52.

However, it would also be possible for the dipole mass vane 9 and the dipole signal vane 11 of the second dipole radiator 3 to be designed as conductor tracks 52c, 52d on a second side 52 "of the third printed circuit board 52.

The first printed circuit board 51 is perpendicular to the third printed circuit board 52. The first printed circuit board 50 is soldered or electromagnetically coupled to the third printed circuit board 52, in particular on the first 5 side 52 'of the third printed circuit board 52 such that the ground terminal carrier 4 of the first dipole radiator 2 is galvanically or inductively or capacitively connected to the dipole ground plane 5 of the first dipole radiator 2 and the signal terminal carrier 6 of the first dipole radiator 2 is galvanically or inductively or capacitively connected to the dipole signal wing 7 of the first dipole radiator 2 is.

The second printed circuit board 51 is soldered or electromagnetically coupled to the third printed circuit board 52, in particular on the second side 52 "of the third printed circuit board 52, so that the ground terminal carrier 8 of the second diode 5 polstrahlers 3 galvanically or inductively or capacitively with the dipole mass vane 9 of the second dipole radiator 3 is connected and that the signal terminal carrier 10 of the second dipole radiator 3 is galvanically or inductively or capacitively connected to the dipole signal vane 1 1 of the second dipole radiator 3. The second circuit board 51 could also be on the first side 52 'as shown in FIG. be soldered to the third circuit board 52 with this or electromagnetically coupled.

FIG. 18B shows that the dipole mass vane 9 of the second dipole radiator 3 dips below the dipole mass vane 5 of the first dipole radiator 2. This can be realized, for example, in that, for example, the dipole mass vane 9 runs in the overlapping area with the dipole mass vane 5 on the second side 52 "of the third circuit board 52, whereas the dipole mass vane 9 Mass wing 5 on the first side 52 'of the third circuit board 52 extends. In contrast, in FIG. 18B the printed conductors 52a, 52c of the dipole earthing vanes 5, 9 of both dipole radiators 2, 3 and the printed conductors 52b, 52d of the dipole signal wings 7, 11 of both dipole radiators 2, 3 with the respective printed conductors 50a, 51a of the ground terminal carriers 4, 8 and the signal terminal carrier 6, 10 of both dipole radiators 2, 3 is soldered on one side 52 ', 52 "of the third printed circuit board 52, in particular on the first side 52' The printed conductor 52c of the dipole mass vane 9 of the second dipole radiator 3 is pierced on the opposite side 52 ", 52 'of the third printed circuit board 52. In this case, the trace 52c of the dipole ground plane 9 of the second dipole radiator 3 changes from the first side 52 'to the second side 52 "of the third circuit board 52 (later, it can be reversed again.) In this area, the trace 52a of the dipole ground plane 5 of the first one runs Dipole radiator 2 continues on the first side 52 'of the third printed circuit board 52. The printed conductor 52c of the dipole dummy blade 9 of the second dipole radiator 3 dips below the printed conductor 52a of the dipole mass vane 5 of the first dipole radiator 2. This situation is shown again separately in FIG.

The third circuit board 52 preferably has engagement openings through which the first and the second circuit board 50, 51 can be plugged. As a result, a higher stability of the cross dipole 1 is also achieved.

FIG. 18D shows a further exemplary embodiment of the crossed dipole 1 from FIGS. 18A to 18C. In this case, the dipole mass vane 5 of the first dipole radiator 2 extends at least over a partial length on both sides

A plurality of further plated-through holes 54 connects the two printed conductors 52a of the dipole mass vane 5 of the first dipole radiator 2. The same also applies to the dipole earth vane 9 of the second dipole radiator 3 and the dipole signal vane 7, 11 both dipole radiators 2, 3.

All the above embodiments would also apply to the arrangement with the circuit boards. FIG. 23 also describes an antenna arrangement 30 which comprises a multiplicity of further cross dipoles 1. The further cross dipoles 1 can be constructed according to one of the preceding examples. The others Cross dipole 1 are arranged in at least two columns 60 next to each other and in the respective column 60 still one above the other. Shown in this embodiment, eight columns 60. In each column 60 a plurality of further cross dipoles 1 are arranged. In this case 60 eight more cross dipoles 1 are arranged in each column. Preferably, in each column 60 as many further cross dipoles 1 are arranged as there are columns 60. In this case, the further cross dipoles 1 are arranged like a checkerboard (in columns 60 and lines 61). In addition to eight columns 60, there are also eight lines 61. However, the number can vary as desired. More columns 60 than rows 61 or more rows 61 than columns 60.

In the mounting position of the antenna arrangement 30, the further cross dipoles 1 are arranged vertically in a column 60 (one above the other) and the further cross dipoles 1 are arranged horizontally (side by side) in a row 61.

A distance of another cross dipole 1 within a first column 60 to its adjacent further cross dipole 1 in the same column 60 preferably corresponds to the distance of another cross dipole 1 in another column 60 to its adjacent further cross dipole 1 in the same other column 60. Preferably, all others are Cross dipoles 1 in each column 60 equidistant from their neighbors. The same preferably also applies to the further cross dipoles 1 in the various lines 61.

The arrangement of these further cross dipoles 1 allows a MIMO operation of the antenna arrangement 30. The further cross dipoles 1 are preferably aligned identically with respect to their dipole signal wings 7, 11 and their dipole mass wings 5, 9. In particular, the dipole signal wings 7, 11 and the dipole wings 5, 9 are rotated through approximately 45 ° to the columns 60 (vertical axis of the antenna arrangement 30) and to the lines 61 (horizontal axis of the antenna assembly 30). A distance of the dipole signal vanes 7, 11 and the dipole mass vanes 5, 9 of the individual further cross dipoles 1 to the main body 15 is preferably the same.

The shown further cross dipoles 1 are in particular designed to be operated in a first frequency range (eg high band). Furthermore, there are other cross dipoles 62, which may also be constructed according to one of the previous examples. These other cross dipoles 62 operate in a second frequency range (eg low band). The second frequency range is lower than the first frequency range. In particular, the center frequency of the second frequency range is below the center frequency of the first frequency range.

The other cross dipoles 62 are constructed in this case according to the example of Figure 15D, to which reference is hereby made. The respective other cross dipole 62 is larger than the other cross dipoles 1. Preferably, it is more than twice or three times as large. This is especially true for the length of the respective Dipolsignalflügel 7, 1 1 and the Dipolmasseflügel 5, 9. These are in the other cross dipoles 62 accordingly (more than 2 times or more than 3 times) longer than in the other cross dipoles 1. Bei This is then the case for the individual wing segments 5 ', 5 ", 7', 7" of the dipole mass vane 5 and of the dipole signal vane 7 of the first dipole radiator 2 and for the individual vane segments 9 ', 9 ", 1 Γ, 1 1 "of the dipole mass vane 9 and of the dipole signal vane 1 1 of the second dipole radiator 3.

The other cross dipoles 62 are arranged in this embodiment between two columns 60 and between two rows 61 of the further cross dipoles 1. Consequently, the other cross dipoles 62 are arranged both horizontally and vertically offset from the adjacent further cross dipoles 1.

The individual wing segments 5 ', 5 ", 7', 7" of the dipole mass vane 5 and the dipole signal vane 7 of the first dipole radiator 2 and the individual vane segments 9 ', 9 ", 1 Γ, 1 1" of the dipole mass vane 9 and the dipole signal vane 1 1 des second dipole radiator 3 of the other cross dipoles 62 preferably run parallel or perpendicular to the gaps 60 (vertical axis of the antenna arrangement 30) or to the lines 61 (horizontal axis of the antenna arrangement 30).

The individual wing segments 5 ', 5 ", 7', 7" of the dipole mass vane 5 and the dipole signal vane 7 of the first dipole radiator 2 and the individual vane segments 9 ', 9 ", 1 Γ, 1 1" of the dipole mass vane 9 and the dipole signal vane 1 1 des second dipole radiator 3 of the other cross dipoles 62 run preferential way in a distance space (between two lines or between two columns) between the other cross dipoles. 1

A distance between the individual vane segments 5 ', 5 ", 7', 7" of the dipole mass vane 5 and the dipole signal vane 7 of the first dipole radiator 2 and the individual vane segments 9 ', 9 ", 1 Γ, 1 1" of the dipole mass vane 9 and the Dipolsignalflügels 1 1 of the second dipole radiator 3 of the other cross dipoles 62 to the base body 15 is preferably greater than (or less than or equal to) a distance between the Dipolsignalflügel 7, 1 1 and the Dipolmasseflügel 5, 9 of the further cross dipoles 1 to the main body 15th

In the case that the antenna arrangement 30 from FIG. 23 has no (other) cross dipoles 62 according to FIG. 15D, but those which do not have any wing segments 5 ', 5 ", 7", 7 "or 9', 9", 1 " , 1 1 ", these other cross dipoles 62 are rotated such that the dipole signal vane 7, 1 1 and the dipole ground vanes 5, 9 parallel to or perpendicular to the columns 60 (vertical axis of the antenna assembly 30) and to the lines 61 (horizontal axis of Antenna arrangement 30) run. A distance between two adjacent (both horizontally adjacent and vertically adjacent) other cross dipoles 62 is greater than a distance between two adjacent further cross dipoles. 1

In this embodiment, there are two columns with other cross dipoles 62, with two other cross dipoles 62 arranged in each column. Consequently, one can also speak of two lines here. But there may also be more columns and / or rows with other cross dipoles 62.

The ground terminal carriers 4, 8 of both dipole radiators 2, 3 of all further dipoles in a column 60 and / or a row 61 are optionally galvanically connected to one another via a connection and together with this compound in one piece from a common bending and / or punching and / or laser and / or edge part formed. The same can also apply to the other cross dipoles 62.

The same could optionally also apply to the signal terminal carriers 10 of the first dipole radiators 2 of the further cross dipoles 1, at least in one column 60. This could also apply to the other cross dipoles 62. In this case, a common supply of the first dipole radiator 2 would take place.

Optionally, this could also apply to the signal terminal carriers 10 of the second dipole radiators 3 of the further cross dipoles 1, at least in one column 60. This could also apply to the other cross dipoles 62. In this case, a common supply of the second dipole radiator 3 would take place.

Preferably, the dual-polarized cross dipole 1 is free of a balun.

Furthermore, it is preferable for each Dipolsignalflügel 7, 1 1 exactly one signal terminal carrier 6, 10 is provided. In this case, there are just as many signal terminal carriers 6, 10 as dipole signal wings 7, 11. Via these signal terminal carriers 6, 10, the feed is also (exclusively) carried out. The same can also apply to each dipole mass vane 5, 9.

The Dipolsignalflügel 7, 1 1 are preferably only with their exactly one signal terminal carrier 6, 10 in contact. You could also be in addition to the signal terminal carrier 6, 10 of the other dipole radiator 2, 3 in contact. This applies when the signal terminal carriers 6, 10 are integrally formed. This can also apply to the ground terminal carriers 4, 8 and the dipole mass wings 5, 9.

The Dipolsignalflügel 7, 1 1 are free of further connections. The same applies to the dipole earthing vanes 5, 9. Additional connections for feeding or contacting with a ground are not provided.
