Abstract

An improved dual-polarized antenna arrangement has four antenna element devices each with a conductive structure between opposite antenna element ends. Those antenna element ends of two adjacent antenna element devices adjacent to one another are, in each case, isolated from one another for radio frequency purposes. Those antenna element ends of two adjacent antenna element devices located adjacent to one another in pairs form feed points, and the antenna element devices are fed at least approximately in phase and approximately symmetrically between the respective opposite feed points.

Description

The invention relates to a dual-polarized radiator arrangement especially for the mobile sector after the Preamble of claim 1.

Dual polarized antennas are preferred in the mobile sector at 800 - 1000 MHz and 1700 - 2200 MHz. In this case, two antennas become orthogonal polarizations In particular, the use has been generated of two linear polarizations with the orientation of + 45 ° or -45 ° proven over the vertical (X-polarization). To the illumination of the supply area too optimize, antennas with different horizontal Half-widths used, with as meaningful gradation Half-widths of 65 ° and 90 ° have enforced.

For antennas with only one polarization exist more Prior art solutions to these different To realize half-widths.

Thus, e.g. simple vertically oriented dipoles with one optimized to the corresponding half width Reflector used as vertically polarized antennas. For antennas with only one operating frequency range also solutions for X-polarized antennas with half-widths already known from 90 °. To do this for example, cross dipoles or dipole squares or patch radiators used with appropriately designed reflector, to achieve a corresponding horizontal half width.

According to DE-A1-197 22 742, this is a reflector geometry proposed, in which in the opposite to the reflector sheet laterally projecting reflector side boundaries Slots are introduced. Will such a reflector geometry for example with cross dipoles or with a special dipole structure, such as DE 198 60 121 A1 is known, used, so can be a horizontal half width between about 85 ° and 90 ° realize. However, this example only concerns an antenna that is only in an operating frequency band is operated.

However, in dual polarized antennas, which in two far operated apart frequency ranges intended, e.g. offset by a factor of 2: 1 solutions are only with horizontal half widths known by about 65 °.

For example, according to US-B-6,333,720 (which is the DE-A1-198 23 749 corresponds) an antenna in the form of a Dipole square proposed, consisting of four pairs each aligned in parallel and offset from each other Dipoles exists. Each dipole consists of two Dipole halves, the center fed via a balancing become. The respective dipole halves are thereby at their facing each other at trained there Anspeisestellen at least approximately in phase and fed approximately symmetrically. In the corner areas of the dipole square are outwards and offset by 90 ° mutually lying dipole ends high frequency from each other isolated.

In addition, in this prior publication, a combination proposed by Dipolstrahlern, which is responsible for both frequency ranges (for example, the 900 MHz band and the 1800 MHz band) has a half width of about 65 ° can be realized.

An appropriate solution using patch emitters is known, for example, from WO 00/01 032.

The realization of antennas operating in two frequency bands or two operating frequency ranges can be operated and thereby have a half-width of about 90 ° are not yet feasible.

In addition, there will also be further pre-releases of antennas, which, however, also not in a half-width of about 90 ° for operation in two mutually offset frequency ranges are suitable. These are, for example, antennas, as stated in the publication S. Maxi and Biffi Gentili: "Dual Frequency Patch Antennas" in: IEEE Antennas and Propagation Magazine, Vol. 6, December 1997 are described. A dual polarized antenna, which has a 3-fold structure and in its polarization Aligned horizontally and vertically is also in Nobuhiro Kuga: "A Notch-Wire Composite Antenna for Polarization Diversity Reception "in IEEE AP Vol. 46, No. 6, June 1998, pp. 902-906 as known. This antenna generates an omnidirectional diagram. But also lets it out Do not remove a dual-band antenna that is a horizontal Half width of about 90 °.

The object of the invention is therefore a radiator arrangement to create, on the one hand for two orthogonal Polarizations can be used and in which at least one Spotlights can be integrated for a higher frequency band range is, with half-widths of about 90 ° feasible should be.

The object is according to the invention in the claim 1 specified characteristics solved. Advantageous embodiments The invention are specified in the subclaims.

By the inventive dual-polarized radiator arrangement For the first time, it will be possible to create antennas which is horizontal in both frequency ranges Have half-widths of 90 °. Regardless of this These radiator structures can also be used at Need to be operated only in one frequency range.

In Figures 1 to 3 is a first embodiment a dual polarized antenna according to the invention shown.

As shown in Figure 1 in perspective, in FIG 2 in a schematic side view (in a sectional view perpendicular through the reflector plane) and in FIG 3 can be seen in a plan view, the inventive Emitter arrangement essentially four radiator devices 1, i. four radiator devices 1a, 1b, 1c and 1d, which are conductive. These four radiator devices 1 form a square in plan view Structure. In other words, the antenna is explained with the Radiator arrangement in plan view by 90 ° rotationally symmetrical or point-symmetrical.

The in plan view forming a square structure Radiator devices 1 can also be used as radiator elements, Radiator arms, radiator rods or generally as Radiator structures are called.

These four in the embodiment shown in the figures 1 to 3 rod-shaped radiator devices 1 point about an equal length of about a 0.2 times to the 1 times the operating wavelength λ. The distance to the Level 3 of the reflector 5 is about 1/8 to 1/4 of the Operating wavelength.

From the described structure, it follows that the im shown embodiment rod-shaped radiator devices 1 parallel to the reflector plane in a common Emitter plane 7 are arranged. Here are the respectively opposite radiator devices 1, ie in the embodiment shown, the radiator devices 1a and 1c parallel to each other. Further, the two in each case offset by 90 ° further radiator devices, So in the embodiment shown the Radiator devices 1b and 1d also parallel to each other arranged. Both pairs of parallel to each other arranged radiator devices 1a and 1c on the one hand and 1b and 1d to the other are perpendicular to each other or at least approximately perpendicular to each other, resulting in an antenna arrangement, which in two send polarizations perpendicular to each other and can receive, in a plane E1, in one Angle of + 45 ° with respect to the horizontal is aligned and in a plane E2, which faces at an angle of -45 ° the horizontal is aligned.

As can also be seen from the exemplary embodiment is, are each opposite, so removed mutually lying ends 9 of the four radiator devices 1, i. the radiator ends 9a, 9a 'and 9b, 9b', and 9c, 9c 'and 9d, 9d' high frequency to the respective adjacent End point of the adjacent radiator device isolated. That is, the radiator end 9a of the adjacent Radiating 9b ', the radiator end 9b from the adjacent Radiating 9c ', the radiator end 9c from the neighboring Radiating 9d 'and the emitter end 9d from the adjacent Emitter 9a 'is high frequency isolated. Each of the four radiator devices 1 each by an electric conductive holding device 17 is held and carried, preferred over the reflector 5. This holding device 17 may in the embodiment according to the figures 1 to 3 per radiator device 1 each consisting of two rods or rod means 19 consist, each of a preferably formed by the reflector base 21 at which mechanically mounted and electrically conductive attached to the radiator devices 1 in divergent Form are guided to the radiator ends 9. The Arrangement is such that each of the adjacent Emitter ends, for example the emitter ends 9a and 9b 'of the mutually adjacent radiator devices 1a and 1b, guided rod devices 19 from their base 21 from parallel to each other at a distance run, whereby between two adjacent lying Rods or rod assemblies 19 each have a slot or Gap 25 is formed.

From the described structure is to be seen on the one hand, that the bars or rod means 19 at the reflector side or base-side end 27 via a conductive base 21, the conductive reflector sheet 5 and / or a conductive Compound 29 are interconnected. As stated, In addition, a line connection is additionally preferred made to the reflector 5 itself. This line connection However, the reflector 5 does not necessarily have to to be available.

Approximately so in the illustrated embodiment according to Figures 1 to 3 by the respective radiator device 1, to the respective radiator ends of the Radiator 1 leading rod or holding device 17, 19 and the base or reflector side lying ends 27 as well as by the optionally provided therebetween conductive connecting means 29 and / or a conductive Base or by the reflector 5 itself a trapezoidal Structure formed.

The inlets of the radiator devices 1 take place in this embodiment at the respective end of the four Columns or slots 25, so at the radiator ends 9. Die Infeed takes place at these four corners or points 13 preferably by means of coaxial cable 31, which in the schematic Top view according to Figure 2 schematically indicated are.

In each case, the inner conductor 31 'with one end of a radiator device 1 and the outer conductor 31 " with the adjacent end of the adjacent radiator device 1 electrically connected. In other words Thus, for example, the outer conductor 31 "of the coaxial cable 31 with the radiator end 9a of the radiator device 1a electrically connected, whereas the inner conductor 31 ' with the adjacent radiator end 9b 'of the adjacent Radiator device 1b is electrically connected.

Thus, each pair adjacent to each other lying ends 9 of the radiator devices 1, ie at the mentioned four points or corners 13 feed points 113 formed, wherein the supply of the radiator arrangement each at these feed points, so on the reflector side repellent end of the slots or columns 25 at the diametrically opposite points or corners, so at the respective column end to the mentioned Feeding points 113 in-phase takes place. This can be, for example by interconnection by means of an equal length Coaxial line from a central feed point respectively. There are thus two central feed points 35a and 35b for each of the orthogonal polarizations, which at the same time have a high decoupling from one another.

Since the bars or rod means 19 of the holding device 17 and thus the slots or columns 25 a length λ / 4 the emitter ends 9 can easily be or short-circuited on the reflector side. These work in this example, thus together with the feeder cables as Balancing.

In the schematic cross-sectional view of Figure 2 the reflector is shown in cross-section, the outside also transversely or perpendicular to the reflector plane 3 extending Side boundary walls 5 'may include.

Hereinafter, a description will be made of a next embodiment Referenced.

Reference to the figures 4 and 5 is another embodiment shown. This embodiment distinguishes from that according to FIGS. 1 to 3 in that the area that passes through the respective radiator device 1 and the laterally at the ends of the radiator devices. 1 attacking rods or rod means 19 and the Rods 19 supporting base 21, optionally through the reflector 5 and / or the mentioned conductive connecting elements 29 is bounded, not vacant or left blank is, but electrically full surface and thus as a closed Surface is designed. This will be four Radiator 1 and radiator structures 1 created, each having a closed surface element 39. In each case the upper boundary edge 1 ' this surface element 39 represents the radiator device 1, comparable to the embodiment of Figure 1 to 3, dar. The lateral boundary edges 19 'provide ultimately the associated slot or its associated Gap 25 limiting rods or rod means 19 is. The lower edge 27 'is comparable to the base or reflector-side connecting element 28.

Another difference of the embodiment according to Figures 4 to 6 to the embodiment of FIGS 1 to 3 is that the surface elements 39 in vertical section are formed edged, the lower base or reflector-side portion 39 'of the surface element outgoing from a central section to the outside slightly divergent runs (for example, in a Angle of 20 ° to 70 °, preferably by 30 ° to 60 °, in particular by 45 °, whereas only one of the reflector spaced outside portion 39 "of the respective Surface element 39 is aligned in the vertical direction, perpendicular to the reflector 5. This opens the possibility that the total length of the slot or gap 25th and thus the total length of the support rods 19 according to Figure 1 comparable boundary edges 19 'also again λ / 4 of the operating frequency is (preferred center operating frequency), so that by the surface elements 39 base or reflector side a short circuit of the radiating overhead, parallel to the reflector running Limiting edges 19 'can be done, causing the actual Radiator devices 1 are formed. The embodiment according to Figure 2 also shows that, of course the embodiment of Figure 1 not with straight running rods or rod devices 19 run must, but that also in the embodiment according to the figures 1 to 3, the rods or rod devices parallel to each other a kinked shape, comparable to the edge 19 'in the embodiment according to the figures 3 to 5, to form a slot 25 may have.

The total height of a radiator element thus formed is by this kinked formation of the individual surface elements 39 lower.

The embodiment according to FIGS. 4 to 6 can also be so be formed that only top-lying rectangular Surface elements 39 "are provided instead of the lower in plan view each trapezoidal shaped surface elements 39 'breakthroughs are provided, with the upper Surface elements 39 "then by lateral support elements 19th being held.

On the basis of the schematic plan view of Figure 7 is only illustrated that the surface elements 39 deviating from the last embodiment explained not over the entire surface must be formed closed, but also For example, be provided with a hole pattern 43. Other modifications are possible and conceivable.

In the embodiment of Figure 8 is a total structure been chosen, in which the individual radiator devices 1 not from straight bars or Limiting edges are formed, but in plan view convex or even part-circular radiator devices 1 form. Would be the crosswise opposed slots or columns 25 not by holding rods or rod means 19 are limited, but these edges are 19 'part of offset by 90 ° surface elements 39, so are this corresponding part-truncated or partially cylindrical aligned running trained.

In an embodiment according to FIG. 9, the Radiator devices 1 not convex but concave. Otherwise in this embodiment as well the overhead radiator device 1 again as electrically conductive, rod-shaped device or the like be formed by corresponding bars or Rod means 19 are held. The in between free Surface can also be completely closed again, so that surface elements 39, comparable to the embodiment are formed according to Figures 4 and 5.

With particular reference to FIGS. 8 and 9, it can thus be seen that the radiator devices 1, e.g. Using of corresponding surface elements 39, the radiator edges 1 ', between the feed points 13, 113 not just run straight, but in Top view viewed from a central middle section convex outward protruding or even concave formed are formed. It can be correspondingly shaped Radiator devices 1 are used or full-surface or partially full-surface radiator elements 1 with surface sections 39 or forming a corresponding Free space 39 '.

It is further explained with reference to FIG. 10 that an improvement The radiation characteristic also realized thereby is that to the possibly rod-shaped Radiator devices 1 or in the case of surface elements 39 at the corresponding the actual radiator devices 1 forming boundary edges 1 'preferred running centrally and parallel to the reflector 5 aligned outwardly projecting electrically conductive connected Lugs or lugs 45 may protrude.

In the embodiment according to FIGS. 11 and 12 is at the outer ends 47 of these tabs or lugs 45 yet another extension 49 is provided, the in this embodiment, in turn, preferably vertically is aligned to the reflector plane 3. It shows the Top view according to Figure 11 also that the pairs in each case offset by 90 ° to each other, preferably in parallel to the reflector plane 3 extending tabs or lugs 45th with different longitudinal extent along the reflector plane can run. The same is true for the preferably provided vertically to the reflector plane 3 extension approaches 49th

On the basis of the illustrated embodiments is therefore a dual polarized antenna, i. a radiator assembly described been working in a frequency band and while large half-widths of, for example, 90 ° can have.

In this case, for example, several such, based on the Figures 1 to 11 explained emitter assemblies in a vertical arrangement one above the other, preferably in front of a common one Reflector 3 may be arranged. Are the mentioned radiator devices 1 or boundary edges 1 'according to the explained embodiments horizontally or vertically arranged to one another, this results in an X-polarized Antenna in which the one polarization in + 45 ° and the other polarization in -45 ° with respect to the horizontal plane is aligned. The polarization directions are correct in plan view so with the course of the slots or Columns 25 match.

In an extended antenna structure but can now an overall antenna array can be constructed that too for operation in two frequency bands or frequency ranges is suitable, which are located away from each other and themselves for example, differ by a factor of 2: 1. With In other words, an antenna can be set up, for example, in a 900 MHz frequency range and a 1800 MHz frequency range or, for example, in one 900 MHz frequency range and a 2000 MHz or 2100 MHz Frequency range is operable.

With reference to the embodiment of FIGS 13 and 14 this is realized by the fact that inside the of Figures 1 to 11 explained dual polarized Radiator arrangement, a further radiator arrangement for operation is provided in a higher frequency band.

In the embodiment according to FIGS. 13 and 14 this is realized by a patch antenna 51, which in plan view for example, has a square structure and in about the height of the boundary edges 1 ', ie the radiator devices 1 can lie.

In the embodiment according to FIGS. 15 and 16 becomes a vector dipole arrangement for operation in the higher frequency band 53 used as they basically look DE 198 60 121 A1 is known. In this vector dipole element 53, the dipole halves are constructive each of two mutually perpendicular Halbdipolkomponenten formed, the interconnection of the Ends of the symmetrical leading to the respective dipole halves or substantially or approximately symmetrical Lines done in such a way that always the corresponding Conduit halves of the adjacent, perpendicular to each other standing dipole halves are electrically connected. The electrical feed of each diametrically opposite Dipole halves for a first polarization and decouples a second polarization orthogonal thereto. The inner antenna element shown in Figures 15 and 16 in the form of an illustrated vector dipole 53 thereby also for sending or receiving X-aligned, so in the + 45 ° and -45 ° opposite the aligned Polarizations suitable. In other words, the polarizations of the inner vector dipole 53 and of the outer from the bottom to the top wedge-shaped antenna element parallel.

Of course, also deviating from the previous explained embodiments, other combinations of radiator types, for example cross dipoles conceivable, which are used and used in the context of the invention can.
