Definitions
- radiator elements which are at least horizontally and preferably symmetrically offset to a vertical axis of symmetry or plane of symmetry, wherein for each polarization the respective radiator elements are electrically connected to the associated output of a phase shifter assembly. This also further compensates for a compensation that drifts apart the illumination area in the electrical Lowering the vertical diagram allows.
- the phase shifter adjustment element 33 is adjusted accordingly.
- the two parallel dipoles 13 of the uppermost dipole square 15 and of the lowest dipole square 15 oriented at + 45 ° are fed with different phases via the two associated outputs of the phase shifter 27 "
- the parallel dipoles 3'b of the third dipole square which are parallel and offset horizontally are fed with different phase angles .
- the parallel dipoles 3a and 3b of the second and third dipole square connected to the feed line 31 via the common branch lines 19 are fed with the same phase angle so the dipole radiator group becomes two and three, ie the respective parallel dipoles of the second and third dipole squares (ie the two middle dipole squares in FIG.
- FIG. 2 a dual-polarized antenna array known from the prior art is shown, in order to explain again the differences to the antenna array according to the invention.
- the antenna array according to Figure 2 now relates to one which is known in the prior art. It differs from the antenna array according to the invention according to FIG. 1 in that not only the two outer dipole squares according to FIG. 1 remain interconnected and thus, in each case two parallel dipoles 13 for the + 45 ° polarization as well as for the -45 ° Polarization are permanently connected to each other, but that now also in the middle dipole squares, the two pairs of parallel dipoles are fed via a common feed line, ie fed with the same phase or with different but fixed and not lowered during the lowering of the radiation pattern phase relationship to each other become.
- the exemplary embodiment according to FIG. 4 has been explained using the additional radiator elements 215 or 215 ', which form a compensation arrangement with which a drifting apart of the polarization-dependent radiation diagrams can be compensated, suppressed or even overcompensated when the lowering angle is changed.
- the two dipole crosses 215, 215 'provided with horizontal offset represent, as it were, a "degenerate dipole square" in which the two parallel dipoles arranged with horizontal offset are fed with a corresponding phase difference.
- the dipole crosses 215, 215 'according to FIG. 4 serving for the compensation can be used within the scope of the invention in addition to the compensation device, for example according to FIG. 1, according to FIG. 3 or according to FIG.
- the respective parallel, in the embodiment shown at an angle of -45 ° aligned dipoles of the dipole crosses 215 and the corresponding patch radiator 215 'of the compensation radiators are in pairs (ie with respect to the two upper and 2 lower radiator structures in Figure 5) connected to a separately provided for this purpose phase shifter assembly.
- the structure is in this case again symmetrical to the in Fig. 5 only partially reproduced embodiment, as otherwise explained with reference to FIG.
- the variant according to FIG. 5 can be used in addition to the compensation device according to FIG. 1, 3 or 7.
