Description

The invention relates to a connection device for producing an electrical connection connection from a connection point to two radiator arrangements arranged offset to one another according to the preamble of claim 1.

Antenna arrays, in particular for base stations of mobile radio communication devices, generally comprise a vertically oriented reflector arrangement, in which a plurality of emitter devices arranged offset one above the other in the vertical direction are provided. These may be simply polarized radiator arrangements or, as a rule, dual-polarized radiator arrangements which radiate polarizations which are offset from one another by 90 °.

Furthermore, they may be antenna arrangements which receive beams only in one frequency band or in a plurality of frequency bands, for which purpose radiator arrangements are provided which are adapted for the corresponding frequency bands. It is in this respect, for example, on the previously published antenna arrangements according to DE 198 23 749 A1.

Finally, in the case of antenna arrangements, in particular in mobile radio communication technology, it is sometimes also desirable to be able to set or preselect a specific emission angle. To change the so-called down-tilt angle, for example, phase shifter arrangements can be used, as are known according to WO 01/13459 A1. By adjusting the phase shifter elements, there is a change in transit time and thus to a phase shift, whereby the Absenkwinkel can be adjusted.

As mentioned, there are also cases in which, for example, a pair of radiator arrangements arranged one above the other are to be operated in a preselectable, but then fixed preset down-tilt angle. It is also possible that, for example via the previously known from the mentioned WO 01/13459 A1 phase shifter not only a single, but for example a pair adjacent, ie vertically stacked emitters are fed accordingly, preferably with fixed relative to each other preset phase, whereby the antenna radiates at a certain predetermined down-tilt angle. If, for example, such a pair of emitters with different phase angles is also driven via the mentioned phase shifters, then a differently larger down-tilt angle can be set, but a relative phase offset and thus a relative different descent angle always remains fixed. This can be realized by that to the one radiator of the radiator pair leading coaxial cable is slightly longer than the leading to the second radiator of the radiator pair coaxial cable, which is generated by the transit time change the desired relative phase offset.

A connection of such a pair of radiator arrangements which can be fed with different phase angles can furthermore be realized in stripline technology.

Frequently, a certain transformation should also be carried out, for which purpose an impedance converter device is required. Again, this impedance conversion device can be realized by stripline technology or by using boards or coaxial cable solutions. If a feed via coaxial line, so for example by using two serially interconnected coaxial line sections with different inner conductor diameter, a desired impedance conversion can be realized.

In a comparatively simple antenna arrangement using stamped dipole radiators, an electric power split on two emitters offset from each other in front of a reflector plate, for example in the form of dipole radiators, can also be realized via an elongate stamped transmission line having an intermediate line section, for example a narrower one Has width. This allows transformation and impedance conversion. By pre-selection of the feed point of a to be connected, ie to be soldered inner conductor cable a Koaxialkabelitung, then the preselectable phase shift for the two radiator arrangements and thus a Preselected Absenkwinkel be set permanently and permanently. An implementation described above has become known, for example, from EP 0 826 250 B1.

DE 43 29 361 A1 discloses a power distributor for transmitting antennas for distributing the transmitter power supplied via a transmitter coaxial cable to two or more antenna coaxial cables leading to different antenna fields. The power distributor is housed in a square housing, at the lower end of a coaxial connection point for feeding and opposite a T-manifold is provided. The outer conductor housing described in this prior publication represents a hollow tube closed in cross-section. An impedance, power and / or phase matching is difficult to implement with such a power distributor.

A coaxial connector is also known from US 5,730,622 A.

The object of the present invention, however, is to provide an improved feed and connection device for each at least one pair of mutually offset radiator devices that can be used for a variety of types of antenna and it should be as insensitive to external influences, such as stray fields.

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

The connecting device according to the invention allows a direct connection with a pair of mutually offset radiator devices, and this in a cost-effective embodiment. In this case, two radiator elements, for example in the form of two dipole arrays, can be connected taking into consideration an impedance, power and / or phase matching. The electrical properties are preferably realized only by a change (in particular a change in cross section) of the outer conductor and / or only by a change (in particular a change in cross section) of the dielectric. This opens up the possibility of using an inner conductor without diameter jumps, which proves to be particularly cost-effective. The connecting device according to the invention can also be used independently of the reflector or reflector type used. Above all, advantages also arise when the solution according to the invention is carried out in a casting technique. This also contributes to a cost effective solution. Above all, the connection module according to the invention is insensitive to external influences, in particular stray fields. It can be used regardless of the reflector type. It creates a direct connection with the respective radiator, in particular dipole radiator.

The solution according to the invention is characterized inter alia by the fact that a housing arrangement is used for the connecting device, which has a bottom and side wall sections with two opposite longitudinal side walls, whereby an elongate receiving space is formed, wherein opposite to the bottom a aufsetzbaren on the housing assembly and the receiving space overlapping Lid is positionable.

This offers the possibility of having full access to the receiving space in order to use the inner conductor holders which ultimately serve as a dielectric, into which the inner conductor is then inserted and held.

This embodiment thus also offers the possibility of making a corresponding pre-selection in order to be able to carry out a corresponding impedance, power and / or phase adaptation. For example, this also makes it possible to easily use a differently configured inner conductor holder which, due to its different cross section or due to the material chosen differently, has a different dielectric constant, which in turn influences the impedance, power and / or phase matching.

Finally, it must be emphasized as particularly advantageous that the connecting device is realized in one piece, namely with an integrally manageable outer conductor housing with integrated inner conductor. As a result, intermodulation problems are avoided, as they often occur in the prior art as disadvantageous and difficult to control.

In a particularly preferred embodiment, the entire outer conductor arrangement is realized in casting technology, wherein the inner conductor technique is effected by inserting an inner conductor or inner conductor wire, preferably without diameter jumps. By using appropriate plastic mounts, ie generally non-conductive elements, the inserted inner conductor of the outer conductor assembly is electrically-galvanically isolated.

At a connection point provided preferably in the middle region of the connection device, the supply can be effected via a coaxial cable.

The arrangement according to the invention can preferably also be realized as a double arrangement, preferably symmetrically with respect to a longitudinally extending vertical plane of symmetry, namely with two preferably centrally located connection points, preferably for two coaxial cables. As a result, a feed to two pairs of radiator arrangements can be created, which act, for example, as a dual-polarized radiator arrangement. Therefore, for each of the two polarizations, a corresponding supply via a separate inner conductor. The outer conductor arrangement is provided for both inner conductors, wherein preferably the two inner conductors are shielded from each other by a longitudinally extending vertical web which is electrically connected to the outer conductor arrangement.

In a particularly preferred embodiment, the connecting device according to the invention is provided as an independently handleable, arbitrarily insertable and attachable to a reflector component. In an alternative embodiment, however, the outer conductor arrangement can also be produced as an integral functional part from home as part of the reflector arrangement, preferably on the rear side of the reflector to the radiator arrangement. In such an embodiment, an inner conductor arrangement merely has to be inserted into the outer conductor arrangement of the connecting device forming a functional part of the reflector, and the functional part thus formed must be closed by placing a cover arrangement.

Since in the inventive solution, both the inner conductor and the outer conductor housing are constructed in one piece and can be handled in one piece, no intermodulation problems occur, which is of great importance in particular in mobile communication technology.

FIG. 1 shows a schematic representation of an antenna arrangement 1 with a reflector 3, namely in the embodiment shown with eight radiator arrangements 5 arranged one above the other with vertical offset. In the embodiment shown, the radiator arrangements 5 consist of a dual-polarized radiator arrangement, for example in the form of cross-shaped radiator arrangements. But it can also other Dipolstrahleranordnungen, for example in the form of a dipole square, a so-called vector dipole according to the prior publication WO 00/39894 A1 or for example also be used in the form of patch radiators, as is well known. In this respect, reference is made to the emitter arrangements known to the person skilled in the art, which can be used for comparable purposes.

In each case one polarization of the radiator arrangement 5 can e.g. fed via a feed network according to Figure 2, which comprises a feed input 7 for each polarization and in the embodiment shown a double phase shifter assembly 9, as is basically known from WO 01/13459 A1. Reference is made in this regard to this prior publication also with respect to the prior art discussed in this prior publication and made the subject of this application.

The feed input 7 is connected to a pointer-shaped adjusting element 11 of the phase shifter assembly 9, which overlaps two stripline sections 13 and 15. Depending on the setting position of the adjusting element 11 while the energy fed through the different runtime lengths in the stripline sections 13, 15 with different phase position supplied to the radiators fed over it. The four outputs 17 of the phase shifter assembly 9 are connected in the embodiment shown in each case via a connecting device 19 according to the invention which is explained in more detail below with the radiators 5 'belonging to a polarization.

A corresponding circuit structure (in Figure 2 not shown) is provided for the radiator 5 "for the second polarization, wherein the radiator for the second polarization in Figure 2 are indicated only by dashed lines.

Subsequently, the connection device 19 is discussed, about which in each case a pair of adjacently arranged radiators 5 'and 5 "is fed.

In the cross-sectional view of Figure 3, the base portions 5a, for example, two symmetries of two adjacently arranged radiator assemblies 5 are shown, which are mounted on the front side of the reflector 3, whereas on the opposite and thus the rear side of the reflector 3, a connection device discussed below in detail 19th for feeding these two adjacent radiator arrangements 5 is mounted.

The illustrated connecting device 19 is designed as a uniformly manageable connection module, preferably in casting, for example, Alugusstechnik. All suitable suitably processed materials come into consideration. For this purpose, the connecting device 19 comprises a housing or a receiving device 19 'with a bottom 19a and a circumferential side wall section extending transversely and in the embodiment shown at least substantially perpendicular thereto, which is divided into the longitudinal side walls 19b and the transverse side walls 19c arranged on the front side. The bottom 19a with the side wall portions 19b and 19c forms the outer conductor 19 ".

Since the illustrated embodiment is for feeding two pairs of radiator arrangements, namely a pair of emitters 5 'for one polarization and a second emitter pair 5 "for a second polarization perpendicular thereto, the illustrated connection module 19 is equipped with a central longitudinal ridge 19d (through which in the shown embodiment runs a central plane of symmetry running transversely to the bottom 19a) which is also part of the outer conductor 19 ".

On the circumferential side wall portions 19b and 19c and the central longitudinal ridge 19d, a lid 19e can be placed to complete the entire assembly to the outside and shield if necessary. The lid 19e fitted in FIG. 4 may be made of a non-conductive material, for example plastic material. Only if additional shielding is desired, this cover can be made of metal, the lid must not only consist of a casting, but can also be made of a folded metal part. Preferably via lateral tabs 19f, which accrue on an inclined ramp or nose 19g, the lid is placed, wherein the holding portions engage behind the nose 19g in the final mounted position or behind.

As shown in particular in the cross-section reproduced Figures 6 and 7, results from the illustrated construction, an outer conductor arrangement with two elongated receiving spaces 27, in each of which an electrically non-conductive inner conductor holder 29 is inserted. This preferably consists of a plastic acting as a dielectric. The holder can be inserted so that it sits permanently firmly in the receiving spaces 27. But even with loose insertion, she would ultimately by touchdown be mentioned fixed in a predetermined position of the mentioned lid 19e.

The inner conductor support 29 has in cross-section fork-shaped side webs 29a, which are outwardly, i. towards the top, slightly diverging. As a result, a slightly V-shaped groove or a slightly V-shaped receiving slot or receiving space 29b is provided, in the region adjacent to the groove bottom side wall sections are formed which extend parallel to each other or even to the groove bottom in turn are slightly divergent, so that after Pushing the cable-shaped inner conductor 33 into the groove bed this is secured against unintentional moving out of the groove-shaped receptacle 29 b.

In addition, it can also be seen from the exemplary embodiments that the cover arrangement 19e, which is preferably made of plastic, is provided with a pair of downwardly projecting ribs 19e ', which engage in the groove-shaped receptacle 29b in the mounted state of the cover and are designed such that they fixed with the lid mounted in the groove-shaped receptacle 29b inner conductor 33 in this groove-shaped receptacle 29b and hold captive. For this purpose, the ribs 19e 'run slightly wedge-shaped in cross-section and have at their leading end a flattened and possibly even slightly concave abutment portion which rests on the inner conductor 33 in the mounted state.

In the embodiment shown, two connection points 35 are provided on the two opposite longitudinal sides 19d, preferably in the middle region, to which For example, from the illustrated radiator or dipole two coaxial cable 37 can be guided. The outer conductors are electrically contacted with the conductive housing of the connection device or the connection module 19, whereas the inner conductors are separately electrically-galvanically connected to it via an electrical cross-connection 39 with the inner conductor 33 exposed at least in this section, preferably by soldering. In the embodiment shown, the inner conductor 33 is provided in the entire length without cable insulation, since the inner conductor 33 is inserted according to embodiment in an acting as an insulation inner conductor holder 29 made of plastic. A transformation or impedance matching is not provided in the embodiment by a cross-sectional change of the inner conductor 33 (which would be expensive), but by corresponding different configurations of the outer dimension or cross-sectional dimension of the opposite longitudinal side walls 19b, which form the outer conductor of the connecting device. In this case, the distance to the bottom 19a is also important, since by changing the distance to the bottom 19a also a contribution to the transformation or impedance matching is made or can be made.

In the exemplary embodiment shown, in particular also from FIG. 4, it can be seen that the electrical connection points 35 for the feed from the coaxial cables 37 are not centrally located relative to the longitudinal direction of the connection module 19, but slightly outboard, so that, for example, the feed path from the connection points 35 to the frontally opposite connection points (that is, at the opposite end faces 19c of the connection module) is of different lengths, whereby the desired, pre-selected by the entire geometric arrangement phase shift for the adjacent radiator and thus a certain Absenkwinkel is pre-impressed. Deviating from the embodiment shown, but the feed can also be done exactly in the center, namely, when both are fed via the connecting device according to the invention adjacent radiator arrangements arranged to be fed with the same phase position.

FIG. 8 shows an enlarged detail of one of the two connection points 35. It can be seen that, for example, the outer conductor is provided with an electrically conductive outer conductor head 43 seated thereon, which is inserted into a corresponding recess 45 at the connection point 35 and is thereby electrically connected to the outer conductor of the connection device formed in the manner of a housing. Of these, the inner conductor of the coaxial cable is electrically separated via an opening in the longitudinal side walls 19b to the respective associated inner conductor 33 and electrically connected thereto. As explained, the connecting device is configured as a double connecting device with two inner conductors 33, in order to feed both perpendicular polarizations of the mutually offset radiators. The connecting device is preferably designed symmetrically to a vertical central longitudinal plane 47 (FIG. 6). The connecting device thus formed is then attached to a suitable location, for example on the back of a reflector 3, for example, welded, soldered or mounted by means of screws or other fastening devices. Deviating from this, it is also possible to explain the explained Connecting device to connect only with the two dipoles, so the radiator or antenna elements, but not with the reflector. In other words, the connecting part can also be mounted so that it does not even touch the reflector, as can also be seen in the cross-sectional view of Figure 3.

On the basis of FIG. 9, a schematic, partial, perspective view is shown on the rear side of a reflector 3 and in FIG. 10, in a schematic cross-sectional view, transversely to the longitudinal direction of the reflector 3, that the connecting device according to the invention, i. the connection module 19 according to the invention, not only as a separately manageable component, but also as in the reflector assembly integrated functional part may be formed, in which the bottom 19a of the connection module 19 is formed by the material of the reflector 3 itself. In other words, the explained as outer conductor serving longitudinal side walls 19b, the transverse side walls 19c and the intended mean longitudinal ridge 19d form an integral part of the entire reflector assembly.

As can be seen from the figures, for example FIG. 3, FIG. 4 or FIG. 5, the illustrated connecting device 19 or the connecting part is fastened by means of two screws 51, for example directly connected by means of the screws 51 to the radiator elements or dipoles, ie in particular to the associated base portions 5a of the radiator device. In this case, both polarizations of the dipole are preferably mechanically connected to the connecting part, ie, with the connecting device by means of a screw and electrically contacted. In other words, a connection with the Outer conductor of the connecting device 19 produced. Corresponding support regions 53 of the connection device 19, which project downwards in the direction of attachment surfaces or base 5a of the dipole devices via the actual bottom 19a, then rest against the reflector rear wall. In other words, in such an embodiment, the bottom 19a of the connection device 19 would not rest on the reflector 3 and would not touch it.

Deviating from the illustrated embodiment, the illustrated connection module 19 can of course also serve to feed a pair of only simple polarized radiator arrangements. Then, the connection module 19 would have only the peripheral outer walls 19b, 19c without center longitudinal ridge 19d. In the single receiving space 27 thus formed only one corresponding inner conductor holder 29 and only one inner conductor 33 would then be laid.
