The invention relates to a dual polarised microstrip patch antenna comprising at least one individual element, each individual element comprising at least one rectangular, preferably quadratic, patch arranged on the upper face of a printed circuit board, having a feed network on the upper side thereof and being metallized on the entire surface of the lower face thereof. The aim of the invention is to improve the polarization isolation, while simultaneously simplifying the feed network. To this end, the feed network is embodied in such a way that the feed is only fed on two corners of the patch, and the at least one patch is modified in such a way that the isolation is improved between the polarizations of at least one antenna element and a plurality of individual antenna elements in relation to a non-modified patch.
A dual-polarized microstrip patch antenna having one or more individual elements with each of said one or more individual elements having at least one rectangular patch arranged on the upper face of a printed circuit board having a feed network on said upper face and having metallization over the entire surface of the lower face, wherein said feed network permits feed to take place only at two corners of the patch, and wherein said at least one patch has modificationsthat improve the isolation between the polarizations of said one or more individual elements, in comparison to an unmodified patch.
