<p>A device for antennas, in particular dual-polarized microwave antennas with single-polarized patches (202, 204, 206, 208, 371, 372, 373, 374), for which antennas reduced cross-polarization and reduced cross-coupling can be achieved without impairing the bandwidth of the antenna or increasing the occurrence of grating lobes. A modification of the traditionally rectangular geometry of the single-polarized patches is carried out. The modification is symmetrical in relation to the plane in which the linear-polarized signal lies for the respective patch. The modification involves the patches narrowing towards the ends along the respective polarization axis (222, 224, 226, 322) in such a manner that side edges (252, 254, 256, 257) which face side edges of adjacent patches are formed. In this way, the coupling between adjacent patches and also the cross-polarization in the respective patch are reduced.</p> |
