Definitions
- the phase position of the transmission from the input of the individual columns or the antenna inputs is preferably of the same size, but in practice the phase position (or the group delay) has more or less strong tolerance-related deviations from the ideal phase position.
- the ideal phase position is given by the fact that the phase is identical for all paths, including with regard to the beam shaping.
- the more or less tolerance-related deviations are additive as an offset or also frequency-dependent due to different frequency responses.
- FIG. 1 shows a schematic top view of an antenna array 1 which, for example, comprises a multiplicity of dual-polarized radiators or radiator elements 3 which are arranged in front of a reflector 5.
- an edge boundary 5 ′ belonging to the reflector can be provided on the reflector 5, which is set up at an angle to at right angles to the plane of the reflector plate.
- these reflector edge boundaries 5 ' are set slightly obliquely outwards in the direction of radiation.
- the antenna array can be operated such that, for example, a pivoting 16.2, 16.3 to the left or to the right relative to the vertical plane of symmetry of the antenna Arrays can be effected, that is, in different azimuth directions.
- the measurement curves (straight lines) shown in FIG. 4 must be changed in their position in accordance with the arrow representation 28 such that the two upper ones Intersect measurement curves in the form of straight lines 30 and 32 with the two measurement curves 34 and 36 lying lower and steeper in FIG. 4 at a common intersection point X, as shown in FIG. 5.
- z. B. by suitable phase actuators in the exemplary embodiment shown, either with respect to inputs 19.1 and 19.4 or with respect to inputs 19.2 and 19.3, a corresponding phase adjustment can be carried out in order to obtain a common intersection according to FIG.
- intermediate lobes 116 can now be generated, as is shown by the diagram according to FIG. 6, for example, in the case that the inputs 19.1 and 19.2 or 19.2 and 19.3 or 19.3 and 19.4 are interconnected. All inputs are preferably supplied with the same power.
- phase adjustment for the intermediate lobes 116 is carried out with the phase actuators from the Butler matrix 17 ', so that these can be used sensibly by combinations of the inputs A and B, B and C or C and D and without further measures on the antenna feed lines ,
- two couplers 111 which are as identical as possible, are now provided, each of which decouples a small part of the respective signals.
- a combination network 27 this is a “combiner”, which is also abbreviated as “comb.” In the drawing), the outcoupled signals are added. The result of the coupling out of the signals and the addition can be measured via an additional connection S on the combination network 27.
- FIG. 8 it is shown how to use an antenna with two polarizations, e.g. + 45 ° and -45 ° the network can combine for phase adjustment of the supply lines.
- the Butler matrix can be implemented on a circuit board together with the couplers and combination networks, since largely identical units (couplers and combination networks in each case) can thereby be produced.
- the expansion compared to the illustration according to FIG. 7 takes place in that the two outputs of the respective combination network 27 and 27 ', for example in the form of a combiner (Comb), with the inputs of a downstream second combination network 27 "also in the form of a combiner (Comb ) summarized and shared Output S can be laid.
- the combination network 27 thus serves to determine the phase position on a radiator element with respect to the one polarization, the combination network 27 ′ being used to determine the phase position on a radiator in question for the other polarization.
