EP3482450B1 - Antenna array with at least one dipole-type emitter arrangement - Google Patents

Description

The invention relates to an antenna arrangement with at least one dipole-shaped radiator arrangement.

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

A so-called vector dipole is, for example, from the prior publication WO 00/39894 A1 known. Its structure seems to be comparable to a dipole square. Due to the specific design of the dipole radiator according to this prior publication and the special feed, however, this dipole radiator acts similar to a crossed dipole that is perpendicular to each other in two standing polarization planes radiates. In terms of construction, it is rather square, in particular due to its outer contour design.

From the WO 2004/100315 A1 a further embodiment of the aforementioned vector dipole has become known, in which the surfaces of each radiator half of a polarization can be largely closed over the entire surface.

Dipole radiators of this type are usually fed in such a way that one dipole or radiator half is connected to an outer conductor by direct current (i.e. galvanically), whereas the inner conductor of a coaxial connection cable is connected to the second dipole or radiator half by direct current (i.e. again galvanically). The feed takes place in each case at the end regions of the dipole or radiator halves facing one another.

From the WO 2005/060049 A1 It is known to carry out an external conductor feed by means of a capacitive external conductor coupling. For this purpose, the respective associated half of the support device of the radiator arrangement can be galvanically connected to ground at the foot area or on the base of the support device, or it can be capacitively coupled to ground.

From the CN 203386887 U a dipole-shaped emitter arrangement is known which comprises two pairs of emitter halves which are arranged rotated by 90 ° with respect to one another, whereby the dipole-shaped emitter arrangement transmits in two mutually perpendicular polarization planes.

Furthermore, a passive beam shaping frame is shown, which is arranged parallel to the radiator halves in the direction of the reflector and spaced apart. In addition, a director is shown which is arranged parallel to the radiator halves, the radiator halves being arranged closer to the reflector than the director.

From the US 2008/0111757 A1 a dual polarized antenna is known. This comprises part-circular radiator elements which are surrounded by a common circular radiator element. All radiator elements are designed without interruption and are arranged on a common plane.

From the US 2011/0043425 A1 an antenna system is known. The antenna system comprises “high band” elements and “low band” elements, the latter being designed in a ring shape. Two ring-shaped "low-band" elements are arranged in different planes and surround a "high band" element. The "low-band" elements are designed to be uninterrupted.

From the US 2006/0232490 A1 an antenna system with a crossed dipole and a microstrip ring is known. The cross dipole is surrounded by the microstrip ring, which can consist of several uninterrupted rings that are arranged in different planes. The lowest ring is fed via four T-shaped feed structures, with a coupling from the lower to the upper ring.

From the CN 101 505 007 A a radiator arrangement is known which is constructed on a printed circuit board. it includes two pairs of radiator halves, which are arranged on a top side of the circuit board. The circuit board is arranged at a distance from a base via a carrier structure. The underside of the printed circuit board arrangement comprises parasitic structures made of an electrically conductive material. These are on a common level.

The EP 2 950 385 A1 describes a multiband antenna. This comprises a dipole antenna structure that is coupled to a ground plane and is designed to radiate electromagnetic waves in a first frequency band. The multiband antenna also comprises an inverted-F antenna structure which is coupled to the ground plane and is designed to radiate electromagnetic waves in a second frequency band.

From the US 2006/114168 A1 an antenna structure is known which has two pairs of radiator halves which are arranged at a distance from the base via a support structure. On the support structure, wings are formed which extend in the direction of the jet halves. Another antenna system extends away from the base in the direction of the radiator half and ends at a distance therefrom.

The WO 2005/122331 A1 describes a dual-polarized antenna with variable beam inclination. The antenna can have dipole radiation elements including directors and can be arranged on a large number of inclined components in order to be able to adjust the downtilt. The directors are arranged above the respective dipole radiators.

From the US 2004/183739 A1 a dual-polarized folded dipole antenna is known. This comprises a first unit which is designed to transmit and / or receive signals in a first polarization direction. There is also a second unit which is designed to transmit and / or receive signals in a second polarization direction. Each unit includes an integrally formed feed section, an input section and a radiation section. The feed section is formed using microstrip technology. The input section includes a balun transformer.

A disadvantage of the radiator arrangements from the prior art is that the radiator arrangements have too small a bandwidth for some applications.

It is therefore the object of the present invention to create a dipole-shaped radiator arrangement which can be used in mobile radio antennas, which has a bandwidth which is higher than in the case of the radiator arrangements known from the prior art.

The object is achieved by the antenna arrangement with at least one dipole-shaped radiator arrangement according to claim 1. In the dependent claims, further developments according to the invention of the antenna arrangement with at least one or at least two dipole-shaped radiator arrangements are specified.

The dipole-shaped emitter arrangement comprises two pairs of emitter halves which are arranged rotated by 90 ° with respect to one another, so that the dipole-shaped emitter arrangement sends and / or receives in two polarization planes perpendicular to one another. Two radiator halves, which form a pair, are arranged diagonally to one another. The radiator halves can be arranged or arranged in a radiator plane at a distance in front of a reflector parallel to the latter. A balancing and / or support arrangement with a first end and a base at a second end opposite the first end serves to hold the two radiator halves, these being arranged at the first end of the support arrangement. The base of the carrier arrangement is fastened or can be fastened to a base body. This is, for example, a circuit board or a reflector, with at least one indirect attachment to the reflector preferably taking place via the circuit board. In order to additionally increase the bandwidth, at least two electrically conductive partial circumferential frames are provided, which are arranged at a distance from one another in the height direction (ie along) the carrier arrangement between the radiator plane and the base, with the at least two electrically conductive partial circumferential frames each defining or delimiting an opening . The at least two partial circumferential frames are aligned approximately parallel to the radiator plane. Each of the two partial peripheral frames includes at least one interruption that extends through the entire width of the partial peripheral frame, so that the respective partial peripheral frame has at least two ends. This achieves a bandwidth not previously achieved. Frequency ranges so far of at least two different Radiators and / or columns or rows were covered by antennas, can now be emitted by a single system. This means that at least one antenna can now be saved, which leads to a large saving in costs. This advantage is also not achieved with an antenna system according to FIG EP 1 496 569 A1 achieved in which below the radiator plane either several passive radiators in the form of closed rings or at least one actively fed radiator, also in the form of a closed ring, is arranged.

According to a preferred embodiment of the antenna arrangement, the at least two ends of each partial peripheral frame formed by the at least one interruption are directed towards one another. This means that the interruption only extends over a smaller length of the corresponding partial circumferential frame (but nevertheless over the entire width). The interruption has a length which can be less than 1 cm, preferably less than 5 mm. Instead of an interruption, one can therefore speak of a slot.

The at least two partial circumferential frames are preferably arranged approximately parallel to one another, but are nevertheless galvanically separated from one another. In particular, with the exception of the interruption, the at least two partial peripheral frames overlap at least completely or at least partially in plan view. As a result, a coupling between the at least two partial circumferential frames can be increased, as a result of which the bandwidth increases further.

According to a further exemplary embodiment, the at least one interruption extends to less than 30%, preferably to less than 20%, more preferably to less than 10%, more preferably to less than 5% of the length of the partial circumferential frame in plan view of the respective partial peripheral frame. In principle, it would also be possible here for the two partial circumferential frames to be arranged rotated relative to one another. Good results are achieved when the interruptions in the at least two partial circumferential frames only partially overlap or are arranged to one another without any overlap. The latter means that in a plan view of the partial circumferential frames, the interruptions are not arranged directly one above the other, that is to say in a straight line that runs perpendicular to the radiator plane.

According to another exemplary embodiment of the invention, each partial peripheral frame has several interruptions, whereby several partial peripheral frame segments are formed. This means that the partial circumferential frame is divided into several partial circumferential frame segments. These partial peripheral frame segments can all be of the same length. In a special exemplary embodiment, however, it is also possible for one of these partial peripheral frame segments to be longer than others or than all of the other partial peripheral frame segments.

The partial circumferential frames with their respective interruption or their respective interruptions are preferably arranged symmetrically to one another. This means that the interruptions of the at least two partial circumferential frames are arranged rotated relative to one another by α = 360 ° / n, where n is the total number of all interruptions is in the at least two partial circumferential frames. In the event that there are two partial circumferential frames and each partial circumferential frame has exactly one interruption, the value 2 is assigned to n. In this case, the interruptions should be arranged rotated by α = 360 ° / 2 (= 180 °) with respect to one another. A corresponding arrangement in accordance with the above formula is also desirable in the event that there are three, four, or five partial circumferential frames.

In a preferred embodiment, the at least two partial peripheral frames are approximately circular in plan view or describe approximately a circle on average. In principle, however, it is possible that the partial circumferential frames also have a different shape, such as a square and / or a rectangular shape. They can also be oval-shaped. In general, an n-polygonal shape is therefore possible. Preferably, however, all partial circumferential frames have the same shape in plan view, and these can be rotated relative to one another. Within this application, mutual rotation is understood to mean that the center points or the focal points of the at least two partial circumferential frames are still arranged one above the other in plan view after the rotation. A straight line running through these points would preferably be perpendicular to the radiator plane. The at least two partial circumferential frames preferably have the same inner and the same outer diameter. However, it would also be possible for only the inside diameter or only the outside diameter to be the same. Furthermore, it would also be conceivable that neither the inside diameter nor the outside diameter of the at least two frames is the same. It is therefore conceivable that all partial peripheral frames have different geometries. It would also be possible for the at least two partial circumferential frames to be arranged offset from one another by a certain length, wherein they still at least partially overlap in plan view. The overlap preferably takes place over the entire length of the partial circumferential frames, with the exception of the respective interruptions, but not necessarily over the entire width. The overlap can also only take place over a section. With the exception of the interruption, the at least two partial circumferential frames are preferably constructed symmetrically, in particular radially symmetrically. The at least two partial circumferential frames are preferably approximately the same width in plan view. It could also be possible that one frame is wider than the other frame. This relates not only to the diameter, but also to the width of the actual frame web of the partial peripheral frame.

In another development, the at least two partial circumferential frames have several frame sections that are contiguous, with the distances between the individual frame sections alternating from a larger distance to a smaller distance and vice versa towards a longitudinal axis that penetrates the center of the dipole-shaped radiator arrangement changed. The individual frame sections are preferably connected to one another via an approximately radially extending connecting section. As a result, the partial peripheral frames can have a meandering or gear-like basic structure in plan view. The at least two partial circumferential frames created in this way, together with their alternating frame sections (with the exception of the Interruption) arranged congruently or rotated to one another in plan view. Depending on how much they overlap, a different height of the coupling can be set.

At least one dielectric is introduced between the at least two partial circumferential frames. The shape of the dielectric is adapted to the shape of the respective partial peripheral frame in a plan view of the dipole-shaped radiator arrangement. The at least one dielectric is arranged congruently or rotated with respect to one or both partial circumferential frames in a plan view of the dipole-shaped radiator arrangement. The height of the coupling can also be adjusted here. The dielectric can also be created in that one or all of the partial circumferential frames are hard anodized, as a result of which an insulating hard anodized layer is formed.

In another exemplary embodiment, the dipole-shaped radiator arrangement also has a director, the director being aligned parallel to the radiator plane. The radiator halves are arranged closer to the base than the director. The director can have a round, rectangular, oval or generally n-polygonal basic structure in plan view. This basic structure is preferably predominantly free of openings.

In order to achieve simple, preferably tool-free assembly, the dipole-shaped radiator arrangement comprises at least one holding and spacing element. This embraces and / or holds the at least two partial circumferential frames. Additionally or alternatively, the holding and spacer element on the outer surfaces of the two outermost partial circumferential frames. The partial circumferential frames are, for example, sandwiched together with a dielectric located between them in the holding and spacer element. The holding and spacer element can also have a holding clamp or have the shape of a holding clamp, this being designed to apply an additional holding force to the arrangement of the partial circumferential frame and dielectric. However, this is not necessary. The retaining clip preferably has a U-shape or a shape similar to this shape.

So that the assembly is simpler and more reproducible, the at least one retaining clip includes a support section. The support section is arranged within the interruption of a partial peripheral frame, as a result of which two end faces of the two ends, which are formed by the interruption on the partial peripheral frame, are supported on the support section. In this way, the individual partial circumferential frames can be aligned symmetrically to one another because preferably at least one support section of a retaining clip engages in each interruption. This also ensures that the partial circumferential frames are arranged non-rotatably on the dipole-shaped radiator arrangement after assembly. In general, it would also be possible for the at least two partial circumferential frames to be releasably connected to the at least one holding and spacing element by means of a clip or snap connection.

In order to further improve the stability of the dipole-shaped radiator arrangement, the holding and spacing element comprises in another embodiment a support profile. The support profile is adapted to the contour of at least one peripheral frame and has a length that corresponds to at least a partial length of the peripheral frame. The inside of the at least one partial circumferential frame is supported on the at least one support profile or on its outside. This increases the stability of the entire arrangement and at the same time it is ensured that the partial circumferential frames are fixed in place after assembly and remain fixed in place.

In order to further simplify the assembly, the at least one holding and spacer element is via a preferably releasable force and / or form-fit connection, which is preferably a clip or snap connection, on one or on all radiator halves or directly on the Support arrangement held. This means that any screw connections can be dispensed with. Other types of force-fit and / or form-fit connection are also conceivable. This includes, for example, the bayonet connection. The at least one holding and spacer element can also comprise a spacer, for example in the form of the dielectric. This is then placed between the individual partial circumferential frames and provides galvanic isolation. The holding and spacer element is preferably produced in one piece together with the spacer or the dielectric. Production is preferably carried out in a plastic injection molding process.

The Figures 1 , 2 and 4th show a three-dimensional representation of an antenna arrangement 20 according to the invention which has at least one dipole-shaped radiator arrangement 1. The dipole-shaped radiator arrangement 1 comprises two pairs 2, 3 of radiator halves 2a, 2b, 3a, 3b. These two pairs 2, 3 of radiator halves 2a, 2b and 3a, 3b are shown in plan view Figure 7C clearly visible, which shows an antenna arrangement 20 with at least two dipole-shaped radiator arrangements 1. These two pairs 2, 3 of radiator halves 2a, 2b or 3a, 3b are arranged rotated by 90 ° to one another so that the dipole-shaped radiator arrangement 1 in two mutually perpendicular polarization planes 4a, 4b (see Figure 7C ) sends and / or receives. The radiator halves 2a, 2b or 3a, 3b are aligned in a radiator plane 5. This emitter plane 5 is for example in Figure 7B which shows a side view of the antenna arrangement 20 with at least two dipole-shaped radiator arrangements 1. The radiator halves 2a, 2b or 3a, 3b can be or are arranged at a distance in front of a reflector 6, parallel to the latter. The reflector 6 is in Figure 2 shown.

The dipole-shaped radiator arrangement 1 also comprises a balancing and / or support arrangement 7, which is referred to below as a support arrangement 7, which has a first end 7a and a second end 7b. The second end 7b is opposite the first end 7a. The Radiator halves 2a, 2b or 3a, 3b are arranged at the first end 7a of the carrier arrangement 7. The second end 7b of the carrier arrangement 7 can be fastened or fastened at least indirectly to the reflector 6. An indirect fastening can be present, for example, when the second end 7b of the carrier arrangement 7 is fastened to a circuit board 21, wherein a metal layer of this circuit board 21 could simultaneously form the reflector 6. Such a circuit board 21 is for example in the Figures 7A to 8C shown. A separate reflector 6 below the circuit board 21 could also be present. A direct attachment to the reflector 6 would exist if the carrier arrangement 7 is attached directly to the reflector 6 with the second end 7b. This fact is in Figure 2 shown. The reflector 6 or the circuit board 21 can also be referred to as a base body. The second end 7b of the carrier arrangement 7 can also be referred to as the base 10.

The carrier arrangement 7 consists and / or comprises a carrier 7c. In particular, the carrier arrangement comprises one carrier 7c for each radiator half 2a, 2b or 3a, 3b. With regard Figure 1 there are therefore four carriers 7c. Each of these supports 7c extends essentially or exclusively parallel along a longitudinal axis 8 (see FIG Figure 7B , 8B ), which penetrates the dipole-shaped radiator arrangement 1 in the middle. The carriers 7c are galvanically connected to the radiator halves 2a, 2b and 3a, 3b at the first end 7a, that is to say at the first end 7a of the carrier arrangement 7. A capacitive coupling of the carrier 7c to the first end 7a of the carrier arrangement 7 would also be possible. Is between two carriers 7c a gap 9 is formed in each case, which preferably extends from the first end 7a to the second end 7b and is used for balancing. The carriers 7 are preferably galvanically connected to one another at the second end 7b of the carrier arrangement 7, that is to say at their base 10.

The dipole-shaped radiator arrangement 1 is preferably fed in such a way that two cables, each with an inner and an outer conductor, are connected to a pair 2, 3 of the radiator halves 2a, 2b or 3a, 3b. The outer conductor of the first cable is connected to a first radiator half 2a of the first pair 2. In contrast, the inner conductor of the first cable is connected to the second radiator half 2b of the first pair 2. In contrast, the outer conductor of the second cable is connected to the first radiator half 3a of the second pair 3. The inner conductor of the second cable is correspondingly connected to the second radiator half 3b of the second pair 3. The inner conductors therefore cross one another. The connection is preferably made at the first end 7a of the carrier arrangement 7. In principle, it would also be possible for the outer conductors to cross one another.

With regard to the feed and the balancing, reference is made to the documents mentioned in the introduction to the description.

With view on Figures 1 , 2 , 4th , 7C and 8C it can be seen that the radiator halves 2a, 2b or 3a, 3b have an essentially square radiator frame 11. The radiator frames 11 of the radiator halves 2a, 2b or 3a, 3b each have a recess 12 which delimit an opening. Each radiator frame 11 is made of four sides, two sides of a radiator frame 11 being arranged parallel to two other sides of another radiator frame 11. There is a gap 13 between two radiator frames 11. This gap 13 merges into the gap 9 of the carrier arrangement 7. More precisely, the gap 13 is formed between two inner sides of the radiator halves 2a, 2b or 3a, 3b, which run parallel to one another. The radiator halves 2a, 2b or 3a, 3b are fed at the point at which two inner sides 11b of a radiator half 2a, 2b or 3a, 3b meet. Each inner side 11b is connected to an outer side 11a. At the point at which two outer sides 11a meet, the outer corner is preferably beveled (not shown).

The radiator halves 2a, 2b or 3a, 3b can also be designed without a recess 12. In the Figures 7C , 8C the sides of the recess 12 are arranged parallel to the sides of the radiator frame 11. The sides of the recess 12 can also be rotated at an angle, in particular of 45 °, with respect to the sides of the radiator frame 11. In this case, the recesses 12 of the radiator frame 11 have the shape of a square when viewed from above. However, they can be generally rectangular or have a different cross section. This means that the recesses 12 can be selected to be different over a wide range with regard to their size and shape.

The radiator frames 11 of the radiator halves 2a, 2b or 3a, 3b are connected at their first corners to the first end 7a of the individual supports 7c of the support arrangement 7.

Another corner of the radiator frame 11 of the radiator halves 2a, 2b or 3a, 3b, which is opposite the respective first corner, preferably diagonally opposite, is optionally beveled. The other corners are preferably less beveled or not beveled. The beveled corners are those corners of the radiator frame 11 which are most distant from the longitudinal axis 8.

In terms of Figures 1 , 2 and 4th At least two electrically conductive partial circumferential frames 15a, 15b are additionally provided, which are arranged at a distance from one another between the radiator plane 5 and the base 10 in the height direction of the carrier arrangement 7. The at least two electrically conductive partial circumferential frames 15a, 15b each define or delimit an opening 17. The at least two partial circumferential frames 15a, 15b are aligned parallel to the radiator plane 5. They are also preferably aligned approximately parallel to one another. The wording "approximately" means that the at least two partial circumferential frames 15a, 15b are also inclined to one another by a few degrees, preferably by less than 5 °, more preferably by less than 3 °, more preferably by less than 1 ° can.

Each of the at least two partial peripheral frames 15a, 15b comprises at least one interruption 16. The interruption 16 penetrates the entire width of the respective partial peripheral frame 15a, 15b at at least one point, so that the respective partial peripheral frame 15a, 15b has at least two ends 18.

The at least two ends 18 of the partial circumferential frames 15a, 15b formed by the at least one interruption 16 are directed towards one another. The interruptions 16 preferably extend only over a certain length of the respective partial circumferential frame 15a, 15b, so that the interruptions 16 can also be referred to as a slot.

The partial circumferential frames 15a, 15b consist of an electrically conductive material or are coated with an electrically conductive material.

The partial circumferential frames 15a, 15b are preferably produced in a stamping process, the respective interruptions 16 also being introduced in this process, for example.

Is not shown in the Figures 1 , 2 and 4th that a dielectric 19 is introduced between the partial circumferential frames 15a, 15b, which also functions as a spacer at the same time, so that the at least two partial circumferential frames 15a, 15b are arranged galvanically separated from one another. In principle, the distance between the individual partial circumferential frames 15a, 15b could also take place via the suspension of the individual partial circumferential frames 15a, 15b. In this case, air would act as a dielectric.

The at least two partial circumferential frames 15a, 15b are in particular also galvanically separated from the carrier arrangement 7 and the radiator halves 2a, 2b, 3a, 3b and furthermore in particular galvanically separated from all other structures.

The at least two partial circumferential frames 15a, 15b are in particular arranged closer to the reflector 6 or the common base body 6, 21, on which the base 10 of the carrier arrangement 7 is arranged, than all (directly) fed radiator halves 2a, 2b, 3a, 3b or . all (directly) fed emitters.

In Figure 3A are the two partial peripheral frames 15a, 15b from the Figures 1 and 2 shown in isolation. In a plan view of the respective partial circumferential frame 15a, 15b, the at least one interruption 16 extends to less than 30%, preferably to less than 20%, more preferably to less than 10%, more preferably to less than 5% of the length of the partial circumferential frame 15a, 15b.

The at least two partial circumferential frames 15a, 15b are arranged rotated relative to one another. This means that the interruptions 16 of the at least two partial circumferential frames 15a, 15b are arranged completely without overlapping with respect to one another. This achieves a very high bandwidth. In principle, it would also be possible for the interruptions 16 to partially overlap. Complete overlapping, that is to say a congruent arrangement of the interruptions 16, is not desirable.

The interruptions 16 of the at least two partial circumferential frames 15a, 15b are preferably rotated relative to each other by α = 360 ° / n, where n is the sum of the common number of interruptions 16 in the at least two partial circumferential frames 15a, 15b. In this case, n has the value two because there are two interruptions in total 16 in the partial circumferential frame 15a, 15b. Consequently, the two interruptions 16 are arranged rotated by α = 180 ° with respect to one another.

With regard Figure 2B the partial peripheral frames 15a, 15b have several interruptions 16, whereby each partial peripheral frame 15a, 15b is divided into several partial peripheral frame segments 15a ₁ , 15a ₂ , 15a ₃ , 15a ₄ ; 15b ₁ , 15b ₂ , 15b ₃ , 15b _{4 are} divided. It is possible that one of the partial peripheral frame segments 15a ₁ , 15b ₁ , of a partial peripheral frame 15a, 15b is longer than the other or the other partial peripheral frame segments 15a ₂ , 15a ₃ , 15a ₄ ; 15b ₂ , 15b ₃ , 15b _{4 of} the respective partial peripheral frame 15a, 15b. Alternatively, they could all be of the same length.

In this case, the interruptions 16 preferably each have the same size. However, they could also differ in their size and shape.

The at least two partial peripheral frames 15a, 15b are approximately circular in plan view. In this exemplary embodiment, the at least two partial circumferential frames 15a, 15b completely, ie completely, cover one another in plan view with the exception of the respective interruption 16. It would also be possible that the at least two partial circumferential frames 15a, 15b only partially overlap in plan view with the exception of the respective interruption 16. This would be the case if a partial circumferential frame 15a is arranged offset with respect to another partial circumferential frame 15b, the offset occurring transversely to the longitudinal axis 8. Furthermore, an only partial overlap could also take place in that the (inner / outer) Diameter of a partial peripheral frame 15a is smaller or larger than the diameter of the at least one other partial peripheral frame 15b. Even over a changing width b of the respective frame web of a partial circumferential frame 15a, 15b, an only partial overlap could be realized.

The width b of the partial peripheral frames 15a, 15b need not be constant. You can change within a partial circumferential frame 15a, 15b over its length.

Other shapes for the at least two partial peripheral frames 15a, 15b would also be possible. For example, in a plan view, these could have the shape of an oval, a rectangle (in particular a square) or, more generally, the shape of an n-polygon.

In Figure 4 a dipole-shaped radiator arrangement 1 is shown which has three partial circumferential frames 15a, 15b, 15c arranged parallel to one another. Each of these at least three partial circumferential frames 15a, 15b, 15c has at least one interruption 16. In Figure 5 the at least three partial peripheral frames 15a, 15b, 15c are shown separately again. All three partial circumferential frames 15a, 15b, 15c define an opening 17 through which the carrier arrangement 7 is guided. The respective interruptions 16 are not shown overlapping. “Overlapping” is to be understood as meaning that the interruptions 16 of three adjacent partial peripheral frames 15a, 15b, 15c are not arranged congruently in plan view. The interruption 16 of the first partial circumferential frame 15a could be arranged at the same point as in plan view the interruption 16 of the third partial peripheral frame 15c when the second partial peripheral frame 15b has its interruption 16 at a different location in plan view.

Preferably, however, the interruptions 16 are always rotated relative to one another in plan view.

The Figures 6A to 6C show a further exemplary embodiment of the at least two partial circumferential frames 15a, 15b. A dielectric 19d, which is preferably made of plastic, is located between the two partial circumferential frames 15a, 15b. The two partial circumferential frames 15a, 15b each have several frame sections 25a, 25b, the distances between the individual frame sections 25a, 25b alternating from a larger distance to a smaller distance towards a longitudinal axis 8 which passes through the center of the dipole-shaped radiator arrangement 1 and vice versa alternates. The two partial peripheral frames 15a, 15b have in the Figures 6A to 6C the shape of a gear, or the individual frame sections 25a, 25b run approximately in a meander shape.

The individual frame sections 25a, 25b are connected to one another via a connecting section 25c. This connecting section 25c preferably runs radially. The at least two partial circumferential frames 15a, 15b each preferably have more than three, more preferably each more than five frame sections 25a, 25b. There are preferably only two different types of frame sections 25a, 25b. There could also be further frame sections 25a, 25b and / or further types of frame sections 25a, 25b. The latter would be characterized by the fact that they are further from the longitudinal axis removed or spaced closer to the longitudinal axis (compared to the other frame sections 25a, 25b).

On average, however, the two partial circumferential frames 15a, 15b with the respective frame sections 25a, 25b still run in a circular manner.

The at least one interruption 16 is made in each partial circumferential frame 15a, 15b in one of the frame sections.

The frame section 25a, which is further spaced from the longitudinal axis 8, can also be referred to as the outer frame section 25a. In contrast, that frame section 25b which is arranged closer to the longitudinal axis 8 is also referred to as the inner frame section 25b. An inner frame section 25b is connected at its ends to two outer frame sections 25a via two connecting sections 25c. The same also applies to an outer frame section 25a, which is connected at its ends to two inner frame sections 25b via two connecting sections 25c.

The shape of the dielectric 19 is adapted to the shape of the respective partial peripheral frames 15a, 15b in plan view of the dipole-shaped radiator arrangement 1. In terms of Figures 6A to 6C the dielectric 19 also comprises sections which are arranged closer to the longitudinal axis 8 than other sections which are further spaced from it. Both sections alternate.

With regard Figure 6A the two partial peripheral frames 15a, 15b are arranged congruently in plan view (except for the interruptions 16), whereas the dielectric 19 has been rotated by a certain angular position with respect to the partial peripheral frames 15a, 15b. If the sum of the inner and outer frame sections 25a, 25b of a partial peripheral frame 15a, 15b is m, then the dielectric 19 would preferably be rotated by an angle β, which is calculated according to β = 360 ° / 2m (here: 11.25 °) .

Figure 6B shows, however, that the dielectric 19 is arranged congruently together with the at least two partial circumferential frames 15a, 15b, 15a, 15b.

Within Figure 6C on the other hand, the dielectric 19 is rotated further in relation to the at least two peripheral frames 15a, 15b than in FIG Figure 6A . In Figure 6C an outer section of the dielectric 19 lies below or above an inner frame section 25b of the at least two partial peripheral frames 15a, 15b. In this case, the dielectric 19 is rotated by an angle γ with respect to the two partial circumferential frames 15a, 15b, which is calculated according to γ = 360 ° / m (here: 22.5 °).

Figure 2 shows an additional reflector 6 on which the base 10 of the dipole-shaped radiator arrangement 1 is arranged. The reflector 6 has a trough shape. This means that the reflector 6 comprises a reflector base body 6a, to which at least two reflector walls 6b are connected. An angle between the reflector walls 6b and the reflector base body 6a is preferably greater than 90 °. The reflector 6 could also lie exclusively in one plane.

The Figures 7A to 7C show the antenna arrangement 20, which has at least two dipole-shaped radiator arrangements 1, the dipole-shaped radiator arrangements 1 are preferably constructed identically to one another and aligned in the same way. The distance between the two dipole-shaped radiator arrangements 1 is preferably set such that MIMO operation (multiple input multiple output) is possible. It could also be selected in such a way that different frequency bands can be served with the different dipole-shaped radiator arrangements 1.

The two dipole-shaped radiator arrangements 1 are arranged on a common circuit board 21 in this case. This circuit board 21 can be screwed onto the reflector 6, as shown in FIG Figure 2 is shown.

Each dipole-shaped radiator arrangement 1 comprises at least two partial peripheral frames 15a, 15b. These partial circumferential frames 15a, 15b are held by at least one holding and spacer element 35. This at least one holding and spacer element 15a, 15b comprises at least one holding bracket 36. This at least one holding bracket 36 engages around the at least two partial circumferential frames 15a, 15b. The at least one retaining clip 36 rests against the outer surfaces 36a, 36b of the two outer partial peripheral frames 15a, 15b. The at least one retaining clip 36 is preferably U-shaped. The retaining clip 36 may have a pretension, so that an additional force on the surfaces 36a, 36b of the two outermost Partial circumferential frame 15a, 15b acts, whereby the at least two partial circumferential frames 15a, 15b are additionally pressed together. This could be particularly desirable when a dielectric 19 made of plastic is arranged between the respective partial peripheral frames 15a, 15b.

The at least one holding and spacer element 35 is preferably produced in one piece together with the at least one holding clip 36 in a plastic injection molding process.

The retaining clip 36 does not necessarily have to be formed on the retaining and spacer element 35. The holding and spacer element 35 could be supported with one end, for example, on the reflector 6 or the circuit board 21 and with the other end hold or encompass the partial circumferential frame 15a, 15b.

The at least one retaining clip 36 also includes a support section 37. The support section 37 is arranged within an interruption 16 of the partial circumferential frame 15a, 15b, or dips into it. As a result, the end faces of the two ends 18, which are formed by the interruption 16 on the partial circumferential frame 15a, 15b, can be supported on the support section 37. This increases the stability of the entire arrangement. Preferably, the retaining clip 36 together with the support section 37 does not protrude beyond the circumference of the at least two partial circumferential frames 15a, 15b.

The at least one holding and spacer element 35 preferably comprises a support profile 38. The support profile 38 is adapted with its outer side to the contour of at least one partial peripheral frame (preferably of all partial peripheral frames) 15a, 15b and has a length that corresponds to at least a partial length of the partial peripheral frame 15a, 15b. The at least one partial circumferential frame 15a, 15b is supported with its inside on the at least one support profile 38. In this case, all of the partial circumferential frames 15a, 15b, 15c can preferably be supported on the support profile 38.

The holding and spacer element 35, together with the at least one holding clip 36, as well as the support section 37 and the support profile 38, is preferably formed in one piece, that is, in one piece.

The at least one holding and spacer element 35, which holds the at least two partial circumferential frames 15a, 15b, is preferably attached to the dipole-shaped radiator arrangement 1 and / or to the base body 6, 21. In order to ensure tool-free attachment of the at least one holding and spacer element 35 to the dipole-shaped radiator arrangement 1, the at least one holding and spacer element 1 comprises a force and / or form-fit connection 39. This force-fit and / or form-fit connection 39 is in particular in shape a clip or snap connection. The at least one holding and spacing element 35 can be held on one or on all radiator halves 2a, 2b, 3a, 3b or on the carrier arrangement 7 via this force and / or form-fit connection 39.

A dielectric 19 is introduced between the two partial circumferential frames 15a, 15b. With such a dielectric it can also be a spacer. As a result, the individual partial circumferential frames 15a, 15b are galvanically isolated from one another. This dielectric 19 or this dielectric spacer can be formed in one piece together with the holding and spacer element 35, to which, as already mentioned, the at least one holding clip 36 with the holding section 37 and the support profile 38 belongs. This also includes the force-fit and / or form-fit connection 37, which is preferably arranged at the opposite end of the holding and spacer element 35 on which the holding clip 36 is formed.
In the embodiment from the Figures 7A to 8C there are four holding and spacing elements 35 in each dipole-shaped radiator arrangement 1.

In terms of Figures 7B and 7C it should be noted that the individual partial circumferential frames 15a, 15b have a larger diameter than is the case with the radiator halves 2a, 2b, 3a, 3b.

The outer diameter of the individual partial circumferential frames 15a, 15b is less than 150% of the wavelength of the center frequency, preferably less than 120%, more preferably less than 100%, more preferably less than 80% of the wavelength of the center frequency and is more than 10% of the wavelength of the Center frequency, preferably more than 40%, or more than 80%, or more than 120%, or more than 140% of the wavelength of the center frequency.

In another embodiment, the outer diameter of the individual partial circumferential frames is 20% to 80% the wavelength of the center frequency. It is preferably 30% to 70%, more preferably 40% to 60% and more preferably 50% of the wavelength of the center frequency.

The inner diameter of the individual partial peripheral frames 15a, 15b can be of a similar order of magnitude. However, it preferably only has a length that corresponds to less than 99% of the length of the outer diameter of the individual partial circumferential frames 15a, 15b. More preferably, the length is less than 95%, more preferably less than 90%, more preferably less than 80%, more preferably less than 70%, more preferably less than 60% and more preferably less than 50% of the length of the outer diameter of the individual Partial circumferential frames 15a, 15b. However, it is preferably greater than 10%, or 20%, or 30%, or 50% or 60% or 70% or 80 of the length of the outer diameter.

Due to the construction of the dipole-shaped radiator arrangement 1 according to the invention, it operates in a very broadband manner and is suitable for use in a frequency range from 500 MHz to 5000 MHz. Frequency ranges whose upper limit frequency is less than 4500 MHz, or less than 4000 MHz, or less than 3500 MHz, or less than 3000 MHz, or less than 2700 MHz can be served, with the lower limit frequency preferably being higher than 500 MHz, or greater than 600 MHz, or greater than 800 MHz, or greater than 900 MHz, or greater than 1200 MHz, or greater than 1500 MHz, or greater than 1800 MHz, or greater than 2000 MHz, or greater than 2500 MHz, or greater than 3000 MHz. In particular, a Frequency range covered from 1400 MHz to 2690 MHz.

The distance between the individual partial circumferential frames 15a, 15b is between 0.1 and 0.5 mm. However, it can also be larger or smaller.

The Figures 8A to 8C also show an antenna arrangement 20 with at least two dipole-shaped radiator arrangements 1. These are constructed essentially in accordance with the antenna arrangement 20, as they are with regard to FIG Figures 7A to 7C has been described, which is hereby incorporated by reference.

In contrast to the previous exemplary embodiment, each dipole-shaped radiator arrangement 1 also comprises a director 30, which is likewise aligned parallel to the radiator plane 5. The director 30 has a round cross-section in plan view. Other cross-sectional shapes are also conceivable. The radiator halves 2a, 2b, 3a, 3b are arranged closer to the base 10 than the director 30. This means that the director 30 together with the radiator halves 2a, 2b, 3a, 3b and the partial surrounding frames 15a, 15b, 15c on the same side of the reflector 6 or, in general, of the base body 6, 21 are arranged at a distance from this. The director 30, compared to the radiator halves 2a, 2b, 3a, 3b and the partial perimeter frames 15a, 15b, 15c, is arranged at the furthest distance from the point of the reflector 6 or the base body 6, 21 at which the second end 7b , so the base 10 of the carrier assembly 7 is attached. The director 30 preferably has a smaller diameter than the partial circumferential frames 15a, 15b.

The partial circumferential frames 15a, 15b, 15c are preferably each made in one piece by a stamping process. The same also applies to the two pairs 2, 3 of radiator halves 2a, 2b and 3a, 3b, which are produced in one piece together with the carrier arrangement 7 in a stamping process. These can also be shaped by an additional bending process.

It should be noted that when dimensioning the length for the individual elements, all intermediate areas are considered disclosed.

The dipole-shaped radiator arrangement 1 is designed in particular in the form of a vector dipole, cross dipole or a dipole square.

The longitudinal axis 8 is also a central axis 8 which penetrates the dipole-shaped radiator arrangement 1 in the middle, namely perpendicular to the reflector or radiator plane 5.
