Definitions

  • the invention relates to a dual-polarized array antenna, in particular mobile radio antenna according to the preamble of claim 1.
  • mobile antennas are usually single- or multi-column antenna arrays into consideration, which usually comprise in each column a plurality of vertically superimposed radiator or radiator devices.
  • dipole radiators can be used here, for example in the form of dipole crosses, dipole squares or so-called vector dipoles, as are known, for example, from WO 00/39894 A1 or WO 2004/100315 A1.
  • other emitters and emitter shapes are also possible, for example patch emitters.
  • It may be a single-band, dual-band or preferably a multi-band antenna arrangement, which is preferably not only in a polarization plane, but sends and receives in two mutually perpendicular polarization planes.
  • These polarization planes are preferably aligned in the manner of a so-called X-polarization, ie that the two mutually perpendicular polarization planes are aligned in a +45 'angle or -45' angle relative to the horizontal (or vertical).
  • Such a prior art dual-polarized array antenna is expected to be capable of producing two coincident or controllable radiation patterns, namely, for each of the two linear polarizations, i. H. for both polarization planes that are perpendicular to each other. These should be electrically independent of each other. On the one hand, therefore, the Wienpolarisationsabstand the radiation must be very large. Furthermore, the coupling between the antenna terminals should be very low, d. H. the decoupling (isolation) should be very high.
  • a group antenna can also comprise several columns next to each other, so that not only the decoupling between two mutually perpendicular polarization planes with respect to the radiators or radiators of an antenna column, but also the decoupling between the same polarizations in radiators are to be considered, in two different antenna columns are arranged.
  • WO 00/31824 A1 has already proposed a group antenna which comprises spatially separated groups of singly polarized radiators for each polarization.

  • a radiator arrangement is provided in the second column, which is fed together with the radiators or radiator arrangements in the first antenna column.
  • at least one radiator or a radiator arrangement is provided in the first antenna column, which is jointly fed with the radiators in the second antenna column. This ultimately serves for beam shaping, but without this an improvement in terms of decoupling can be realized.
  • an antenna array is proposed with dual-polarized radiators, each having at the edges of a region with single-polarized radiators with the same polarization.
  • the number of emitters that are interconnected in a group is different. This is also intended to produce a different radiation pattern.
  • a two-column antenna is proposed in which, for example, in the first column only emitters are aligned in one direction of polarization and in the second column, the emitters only in a perpendicular polarization plane, wherein the distance of the aligned with the same polarization plane emitters in the two Antenna gaps are different from each other. All these measures serve, as mentioned, to produce different radiation patterns.
  • a generic antenna array according to FIG. 10 has, for example, a plurality of radiator devices 3 which are embodied as dual-polarized radiator devices and comprise radiators or radiator elements 3a which are fed in a first polarization plane PI, ie transmit and / or receive, and second radiators or radiator elements 3b, which receive and / or radiate in a second polarization plane P2 perpendicular to the first polarization plane PI.
  • both polarization planes are aligned at a plane angle of + - 45 'in the vertical or horizontal.
  • the radiator devices mentioned and shown in FIG. 10 are arranged next to one another in a mounting direction 5 (linear arrangement), in the embodiment shown above one another.
  • a single-column antenna is spoken, so a group antenna with an antenna column 7, which is usually aligned in the vertical direction or predominantly in the vertical direction, but in principle can also be aligned in a horizontal direction and in any other direction with a vertical and horizontal component.
  • the following is always always spoken of an antenna column regardless of the orientation.
  • the mentioned radiator devices 3 are usually arranged in front of a reflector 1.
  • the dual-polarized radiators may, for example, be dipole-shaped radiation devices, for example dipole crosses, dipole squares, vector dipoles, etc., as are known, for example, from the cited WO 00/39894 A1. Also Patchstrahler and other radiator devices come into consideration. There are no restrictions in this respect.
  • a dual polarized antenna with similar, i.e. So at least very similar radiation diagrams generated for both polarizations.
  • such an antenna arrangement has approximately equal half widths for the radiation pattern in one polarization plane PI as well as in the other polarization plane P2.
  • the radiators 3a are fed with respect to the one polarization plane PI via a network Nl, whereas the radiators 3b, which radiate in the second polarization plane P2, are fed via the network N2.
  • a dual-polarized antenna arrangement in various embodiments has also become known from WO 2008/060206 A1.
  • an asymmetrical antenna is described which, for example, comprises dual-polarized radiator arrangements which are arranged at a distance from one another in front of a reflector in a mounting direction.
  • six radiators are provided in one polarization plane, whereas eight radiators are provided in the second polarization plane perpendicular thereto, for which an additional radiating element lying in the same plane of polarization is provided above and below the dual-polarized radiators.
  • an improved antenna array which may be formed in principle single-column or multi-column, and which can be operated in a band or preferably in several bands, with simple means improved decoupling between the polarizations of dual-polarized radiator in a column and / or an improved decoupling with respect to radiator device of the same plane of polarization in adjacent antenna columns should be achievable.
  • the antenna array according to the invention is similar to the generic state of the art (as described with reference to Figure 10 of the present application) for both polarizations (polarization planes) preferably produce a similar and / or symmetric radiation pattern, in which therefore the half-widths of the radiation patterns for both polarizations are as far as possible of the same order of magnitude.
  • the object is achieved with the features specified in claim 1.
  • Advantageous embodiments of the invention are specified in the subclaims.
  • a dual-polarized array antenna comprises three different areas or three different radiator arrangements or types of feed of the beam arrangements, wherein it is provided that at least one and preferably a plurality of radiator installations with respect to both mutually perpendicular polarization planes be fed, and that each antenna column is assigned at least in each case a further additional radiator device, which on the one hand only in the first Polarization level and on the other hand fed only in the second polarization plane.
  • the additional radiator arrangements may be simply polarized radiators or also dual-polarized radiators which, in deviation from the other radiators, are only fed into one polarization plane.
