Description

Dipole radiator arrangement

The invention relates to a dipole radiator arrangement according to the preamble of claim 1.

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.

A so-called vector dipole has become known, for example, from the pre-publication WO 00/39894. Whose structure appears to be comparable to ^"a dipole square. Due to the specific design of the dipole radiator according to this prior and the particular energiser but this dipole antenna acts like a Kreuzdi- pol, which radiates in two mutually perpendicular polarization planes. Structurally, it is particularly due its outer contour design rather square. From WO 2004/100315 Al a further embodiment of the above-mentioned vector dipole has become known, in which the surfaces of a respective radiator half of a polarization can be closed to a large extent over the entire surface.

Such dipole radiators are usually fed in such a way that a dipole or radiator half is connected to an external conductor in a DC manner (ie galvanically), whereas the internal conductor of a coaxial connecting cable is connected to the second dipole or radiator half in a DC manner (ie in turn galvanically). The feed takes place in each case at the mutually facing end portions of the dipole or radiator halves.

It is known from WO 2005/060049 A1 to carry out an external conductor supply by means of a capacitive outer conductor coupling. For this purpose, the carrying device or the respectively associated half of the carrying device of the emitter arrangement can be capacitively coupled to ground at the foot region or at the base of the carrying device (in which case the outer conductor of a coaxial feed line is usually below the base of the carrying device) the reflector is electrically-galvanically connected).

With reference to FIG. 1 a, a conventional supply of such a dipole, which is known from the prior art, is shown in a sectional view, specifically for a radiator arrangement 1 which in concrete consists of a dipole I ¹ and for this purpose comprises two radiator halves ^{1 a} and ¹ b, respectively ie in the concrete two dipole halves l'a and l'b. From the sectional view according to FIG. 1a, it can be seen that that this radiator arrangement 1 can be arranged on a reflector 105, for example such that the radiator arrangement 1 with its underlying base 7 is DC-connected (ie galvanically) to an electrically conductive reflector 105 (which forms a ground or ground surface 5). If an insulating layer 21 is arranged between the base 7 and the reflector 105, a capacitive coupling could also be realized thereby. If the electrically conductive base of the radiation device is galvanically separated from the ground or reflector surface by an insulating layer, an electrical-galvanic connection with the support device could be realized, if desired, by virtue of the base 7 of the dipole halves 1 a and l'b holding support 9 DC-coupled (ie galvanically) with ground.

In the same way, the left-hand half 9 ^{1 of} the carrying device 9 (which in the exemplary embodiment shown is hollow-cylindrical, for example) may be extended through a bore in the reflector toward the bottom or rear side of the reflector or at least in the region of the recess or bore in the reflector Reflector so that (when the support device is galvanically decoupled from the reflector ^" , for example by the use of an intended between the reflector and the base of the support means of the radiator isolation) a first feed line (in particular in the form of an outer conductor of a coaxial cable) here at the level of the conductor plane or the reflector is preferably electrically galvanically connected to one half 9 'of the support means 9 to feed the first dipole or radiator half Ia, l'a over this, as all of WO 2005/060049 Al is known.

From FIG. 1a and from the cross-sectional view according to FIG. 1b (FIG. 1b thus shows a cross section along the line II-II in FIG. 1 and also relates to a dipole radiator known from the prior art), it can be seen that in one rather tubular half 9th 'the support means 9 an axial bore 11' is provided, which is ultimately an outer conductor of a coaxial line, wherein from the back of the reflector, an inner conductor 13 is laid to power the radiator arrangement, which in a reflector plane or to the base 7 of the radiator arrangement spaced , the radiator halves Ia and Ib closer eating plane 15 is laid in the direction of the second radiator half Ib, where the inner conductor 13, for example, at the feed point 17 DC, so it can be galvanically connected to the second radiator half Ib. If you would otherwise lay an outer conductor, so use a coaxial feed cable, the outer conductor of such a coaxial cable would be laid, for example, in the bore 11 ', the outer conductor then be galvanically connected, for example, approximately at the level of the feed plane 15 with the first radiator half Ia could. As mentioned but half in question can here 9 'of the carrying device ^"9 itself is used as line-to-line.

According to WO 2005/060049 is reproduced in a modified embodiment that in the second half 9 "of the support means 9 also an axial bore 11" is provided so that a coaxial line arrangement is formed here, namely with an inner conductor 13, via the first bore 11 'in the first half 9' of Carrying device 9 from a matching network; on the underside of the reflector 105 and here forms a first inner conductor section 13a, wherein the inner conductor 13 then passes over an at least approximately parallel to the reflector 105 extending inner conductor or connecting portion 13b in a third inner conductor section 13c, which from above into the second hole 11 "of the second half 9" of the support 9 is immersed and about 9 in the lower third of the height of the Tra- 9 ends freely, without contacting the electrically conductive support means 9. This is preferably ensured by using an insulator which is inserted in the holes 11 ', 11 "and which is penetrated and held by the inner conductor 13. In other words, the central inner conductor section 13b is not galvanically connected to the feed point 17 associated dipole half Ib, l'b, but it is here an internal conductor coupling realized.

Another prior art is known from US 4,668,956. This prior publication shows a dipole radiator, which according to one embodiment comprises two dipole halves and in a further exemplary embodiment has two dipoles offset by 90 ° relative to one another. The respective dipole radiator comprises a tubular support means, which is electrically-galvanically connected to the reflector. Within this serving as outer conductor support means, an inner conductor is guided, which projects on the rear side of a hollow cylindrical Tragage direction and is fed there. The inner conductor is guided at the level of the dipole halves approximately parallel to the reflector plane in the direction of the second half of the hollow cylindrical support means to there in the second -S

hollow cylindrical support back towards the reflector. The inner conductor ends there at a distance from the reflector plane and is electrically-galvanically connected via a short-circuit element with the hollow cylindrical, electrically conductive carrier half.

At the two hollow cylindrical support means in each case at the level of the reflector remote end is formed a projecting parallel to the reflector plane electrically-electrically conductive approach to which attack the dipole halves.

Object of the present invention is to provide, starting from the above-mentioned prior art, a dipole-shaped or dipole-like radiator arrangement, which has an even higher bandwidth.

The object is achieved according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

According to the invention it is now provided that the processing in the prior art in the second half of Trageinrich- free ^"ending inner conductor is formed elongated and direct current (ie galvanically) is connected to ground potential. In other words, the one end of the inner conductor (such as in the state of the art) are connected to the feed network, whereas the other end of the inner conductor is now connected to earth in a DC-current manner.

With this completely surprising structure, a significant improvement in the bandwidth of such a Spotlight realized. The infeed of the radiator continues to be effected by means of a non-galvanic inner conductor feed, whereby also different materials (such as aluminum, plastic provided with a metallized surface, etc.) can be used for the radiators since no solder joints are necessary.

In contrast to the solution according to US Pat. No. 4,668,956, according to the invention, a dipole-shaped or dipole-like radiator arrangement is used which radiates, for example, in one or two polarization planes, the radiator arrangement comprising the dipole and / or radiator halves and the carrier device including the base being altogether electrically conductive , but nevertheless galvanically isolated from the reflector or ground plane, so here is preferably capacitively coupled to the ground or reflector surface. Moreover, according to the invention, the end of the inner conductor (ie, at the opposite end for feeding in a corresponding signal), which is returned to the ground or reflector surface, is then not electrically-galvanically connected to the hollow-cylindrical support device surrounding the inner conductor, for example, but connected to the ground and / or reflector surface.

In a particularly preferred embodiment, the base of the support means of the radiator assembly is capacitively coupled to the reflector or the ground.

However, it is also possible to connect the base of the support means of the radiator galvanically with the reflector or to ground. Even if the base of the support means of the radiator arrangement is capacitively gekoppel with ground or the ground surface, it is preferably provided that the length of the inner conductor and thus the height of the feed plane at a distance from the reflector or ground plane is usually chosen so that it is approximately in Height of the dipole or radiator halves is. Often, this food level will be slightly lower. The feed plane may, for example, preferably lie at any height between λ / 10 below the radiator plane and λ / 6 above the radiator plane, but preferably not higher than λ / 10 above the radiator plane. Λ represents a wavelength of the frequency band to be transmitted, preferably at least approximately the mean wavelength of the frequency band to be transmitted.

The radiator height can be in the usual range of λ / 4 above ground (ie the reflector or the ground). It should, however, have a value of. λ / 10 preferably not lower. In principle, there is no restriction upwards, so that the radiator height could basically be an arbitrary multiple of λ (especially since a radiator has a radiation diagram even without a reflector). However, λ represents only one wavelength from the frequency band to be transmitted, preferably ^" in a middle frequency of the frequency band to be transmitted.

The invention will be explained in more detail with reference to an embodiment. In detail:

FIG. 3 shows a spatial representation of a dual-polarized emitter, in the interior of which an internal conductor feed according to the invention is provided;

Figure 4: a section through the embodiment of Figure 3; and

Figure 5: a bottom view of a matching network on a board, on the opposite side in the longitudinal direction a plurality of radiators are arranged with the inner conductor feed according to the invention.

The structure according to the invention of a dipole radiator 1 according to the invention is now shown with reference to FIG. 2, the reference numerals assigned with regard to FIG. 1 reproducing the same or similar parts.

The exemplary embodiment according to FIG. 2 differs from that according to FIGS. 1a and 1b in that the radiator device, including the radiator and / or dipole halves, as well as the associated support device with the associated base do not electrically-galvanically connected, but is always separated from the ground or reflector surface. However, a capacitive coupling can preferably exist between the ground or the ground surface, that is to say in particular the reflector surface and the support device.

On the other hand, the embodiment according to the invention according to FIG. 2 differs from that according to FIGS. 1a and 1b in that now the inner conductor 13 does not terminate freely in the second carrier half 9 "but extends to the plane of the reflector 105 and with its inner conductor end 19 "DC-connected, that is galvanically connected to the ground plane 5, which is formed either by the electrically conductive reflector 105 or by an electrically conductive ground surface 5 on a board 205, so an electrically non-conductive substrate (dielectric). Usually, the ground plane 5 is formed on the radiator side 205a, whereas on the opposite side 205b, which forms the underside, the matching network 37 is provided, with which the further end 19 'of the first inner conductor section 13a is electrically connected and connected thereto.

In this exemplary embodiment, it is indicated that the base of the carrying device 9 (which is sometimes referred to below as carrier 9) which is electrically conductive or provided with an electrically conductive coating is capacitively coupled to the ground surface 5, for which purpose a plate, plate or foil-shaped one Insulator 21 is provided between the underside of the base 7 of the dipole radiator 1 and the ground surface 5 and the reflector 105. Over the entire length of the inner conductor 13, it is guided electrically-galvanically separated from the carrier 9, usually by inserting insulator sleeves in the axial bores 11 'and 11 ", which are penetrated by the inner conductor 13 be that the inner conductor 13 can make no direct current (galvanic) contact with the electrically conductive support 9.

For this purpose, 9 holes or passages 109 are finally formed at the upper end of the support means to the inner conductor of the one half 9 'of the support means 9 transverse to the other half 9 "of the support means 9 along the so-called feed plane 15, wherein the inner conductor from above Coming into the axial bore 11 "of the second carrier half 9" is immersed.

In this case, according to the exemplary embodiment according to FIG. 2, the position of the line section of the central or second inner conductor section 13b running essentially parallel to the ground plane is defined as the feed plane 15 with respect to the ground or reflector plane. However, this central inner conductor section 13b does not necessarily have to run parallel to the ground or reflector plane. It may be provided between the curvature or transitional portions to the first and third line sections 13a and 13c (which run in the two carrier halves 9 'and 9 ") in side elevation with a central elevation or a central recess to accommodate a transversely to create extending middle line section for a second plane of polarization, for example, when used in two perpendicular polarization planes radiating dipole radiator becomes. Therefore, as the feed plane, either the position of the middle section of the second inner conductor section 13b, which is preferably parallel to the ground or reflector plane, or the center of this central inner conductor section 13b could be used, in order to define the so-called feed plane 15.

2, the two carrier halves 9 ¹ and 9 "are separated from each other by a slot 10 running from top to bottom and connected to one another only by the base 7 located at the bottom, this unit comprising the two carrier halves 9 ¹ and 9 "and the base 7 may be made of a total conductive metal, for example, a metal casting. It is also possible that the two carrier halves 9 'and 9 "with their associated base 7 are made of an electrically non-conductive material, for example of a dielectric, plastic, etc. In this case, the surface is usually complete with a electrically conductive layer, in particular a metallizing layer, coated or covered, which covers not only the outer surfaces, but also the surface of the holes II ¹ and 11 "in the carrier halves 9 ¹ and 9", which ultimately with the inner conductor laid therein inside In this case, the dipole or radiator halves Ia and Ib lying in the radiator plane are preferably also integrally connected to the carrier halves 9 'and 9 ", ie produced together. If the overall structure is not made of an electrically conductive material, the dipole and / or radiator halves Ia and Ib are also coated with the electrically conductive, preferably metallic layer. With In other words, the dipole and / or radiator halves of the associated carrying device, including the carrier halves and the base, are designed and / or connected in an electrically-electrically conductive manner.

3, a dual-polarized emitter 1 "is reproduced in a spatial representation, the principle of which is known from WO 00/39894 A1, WO 2004/100315 A1 and WO 2005/060049 A1 Vector dipole 1 ", which radiates in two mutually perpendicular polarization planes. The two polarization planes P are indicated schematically in FIG. As is known, they run through the vertices of the radiator arrangement designed in a dipole-like plan view, whereby two pairs of radiator halves 1 a and 1 b offset from one another are formed, the second pair of radiator halves 1 a and 1 b additionally being labeled laa and lbb. each fed via a suitably trained inner conductor supply.

In the sectional view according to FIG. 4, the cutting plane runs along a polarization plane P.

It can be seen that the design and installation of the inner conductor 13 with respect to the one polarization plane is analogous to the one explained with reference to Figure 2 emitter array 1 in the form of a simple dipole 1 '. According to this embodiment, the inner conductor 13 extends with its first inner conductor section 13a within an axial bore 11 'of the first carrier half 9' and is preferably separated there from the carrying device 9 by an insulating sleeve 12. At the upper end of the insulating sleeve, the second inner conductor section 13b extends at a right angle to the first inner conductor section 13a, ie parallel to the plane of the ground plane 5 or the reflector 105 and thus also parallel to the radiator halves 1a, 1b in the direction of the second carrier half 9 ", where the inner conductor merges into its third inner conductor section 13c, which in turn runs parallel to the first inner conductor section 13a, ie in turn approximately at right angles to the second inner conductor section 13b and thus aligned at right angles to the ground plane 5.

The first inner conductor section 13a is again guided at the lower end 19 'via a bore 35 (as shown in FIG. 2) in the direction of the reflector 105 or the ground surface 5 and preferably electrically on the back or underside with the matching network 37 already mentioned connected, over which the inner conductor is fed.

The second end 19 "of the inner conductor 13 in the second carrier half 9" is in this embodiment also passed through an electrically non-contact bore 35 'through the reflector 105 and the board 205 and DC (galvanic) on the back of the board 205 via an electrical Connection 23 electrically-galvanic, ie DC-connected via several subsequent vias 25 with the provided on the radiator side 205 a ground plane 5 DC (ie galvanically) contacted. The aforementioned electrical connection 23 may be designed planar, but may also take any other form. Equally, however, the inner conductor could also be galvanically connected directly to the ground plane 5 on the upper side of the board (as shown in FIG. 2). The connection with the ground plane 5 via a formed on the back of the board electrical connection 23 has been selected in the Ausfügungbeispiei shown only for simpler manufacturing reasons.

Also in this case, the feed plane 15 is reproduced (at least approximately) with the central inner conductor section 13b.

In the case of a vector emitter, as shown in the sectional illustration according to FIG. 4, two emitter halves 1a, 1b (or laa, 1bb) are provided for each polarization plane P, each emitter half being mechanically and electrically galvanically connected to an associated carrier half 9 ' and the two pairs of carrier halves 9 ', 9 ", which are each offset by 90 ° relative to one another-corresponding to the respective polarization P offset by 90 ° to one another-are electrically-galvanically connected to one another via their common base 7 located below. the arrangement is preferably such that - in particular, when the ground plane 5 is formed by an electrically conductive reflector 105 - between the electrically conductive base 7, the support means 9 and the ground surface 5, an insulator 21 is positioned, so that the base 7 Gleichstrommäßig is not contacted with the ground surface 5, so there is no galvanic connection ,

If the ground plane 5 is formed, for example, on a substrate 205, then it may also be coated with an insulating lacquer layer, so that a radiator constructed thereon generates a capacitive coupling via its conductive base 7 with the ground plane 5 separated by the lacquer layer. With regard to the radiator halves Ia and Ib reproduced in section in FIG. 4 with respect to the polarization plane P lying in the plane of the drawing, the support half 9 "reproduced on the right in section could be projected from the height of the radiator plane with additional consideration of the base 7 to the contact point 9'a on which the right half carrier 9 "is electrically connected to the base 7, interpreted as symmetrization with respect to this polarization plane. The same applies to the exemplary embodiment according to FIG. 2.

Since the exemplary embodiment according to FIGS. 3 and 4 is dual-polarized radiators, the structure is identical with respect to the second support device 9 rotated by 90 ° with the associated carrier halves 9 ¹ , 9 "for the second polarization plane P, the inner conductor being identical there 13, ie, the two inner conductor sections 13a and 13c extending in the carrier halves are formed only in a slightly larger (or smaller) longitudinal extent, compared to the carrying device 9 offset by 90 °. This has the consequence that in each case the central inner conductor section 13b (which connects the two mutually parallel inner conductor sections 13a, 13c in each case) lies in a slightly offset feed plane 15 ', as a result of which the two central inner conductor sections 13b run at a different height relative to the ground surface 5, where they cross over without contact FIG. 4 is In any case, the corresponding central inner conductor section 13b, which is additionally provided here with the reference symbol 13 'b, becomes visible for the second polarization plane. Alternatively, the respective central crosswise inner conductor section 13b could be of which one polarization plane has a middle section, which rises more towards the top and the second central inner conductor section for the second polarization intersecting therewith has a section curved downwards, so that both inner conductor sections can be laid crosswise without contact, and this with a total of the same length first and third inner conductor sections 13a and 13c.

As a result of the described construction with the inner conductor laying according to the invention, the two ends 19 'and 19 "are led as far as the rear side of the reflector 105 or the rear or lower side of a dielectric substrate 205. In addition, the dipole radiator can also be fixed mechanically, if namely For example, the one feed end 19 'of the inner conductor 13 is soldered on the back of the reflector 105 or the substrate 205 on the matching network 37, for example, and the second end 19 "of the inner conductor 13 is soldered to the aforementioned electrical connection düng 23, about what subsequent Durchkon - Taktierungen 25 then the connection to the ground surface 5 on the radiator side of the substrate 205 is made.

In addition, however, it is also possible to use a screw connection, for example using a screw 51 screwed into the base from the rear side of the reflector or substrate, which may be electrically conductive or electrically non-conductive depending on the capacitive or galvanic application. Likewise, however, adhesives or double-sided adhesive tapes or adhesive films may also be provided between the lower side of the base and the upper side of the reflector or of the substrate for fixing the emitter arrangement. The length of the inner conductor 13, ie the length of the inner conductor section 13a or 13c, should have a length, for example, from a respective foot point 113 'or 113 "at the level of the ground surface 5 to the level of the feed plane 15 or 15' not more than λ / 10 below the radiator plane defined by the radiator halves 1a and 1b (or dipole halves 1a and 1b) and not more than λ / 6 above this radiator plane. if this is not more than λ / 10 below the radiator plane and not more than λ / 10 above the radiator plane, λ represents a wavelength of the frequency band to be transmitted, preferably the average frequency of the frequency band to be transmitted.

Regardless, the distance of the radiator or dipole halves 1 a, 1 b or 1 a or 1 b to the ground surface 5 and / or the reflector 105 may be dimensioned so that this distance is preferably in a range of about λ / 4 above ground or the reflector is located. This radiator height should preferably not fall below a value of λ / 10. By suitable balancing, feed variants and / or suitable matching networks, an even lower emitter level can possibly be achieved (planar antenna).

The mentioned matching circuit or the matching network 37 is provided in order to be able to make a suitable adaptation and transformation here in the base point region of the inner conductor 13 or of the inner conductor section 13a. FIG. 5 shows a section of a bottom view of, for example, the reflector 105 or the substrate 205 with a matching network 37. Here, for the two polarisa- In each case, the lower connecting end 19 'of the inner conductor section 13a and the respective other second end 19 "are connected to one another, which are connected to earth via the electrical connecting device 23 and the following through-connections 25.
