Abstract: The antenna element comprises: an electrically conductive ground plane (2) on which two orthogonal symmetrically crossing slots (3) are formed; a radiating patch (1) supported in a spaced relationship on the one side of the said ground plane; conductive feeding tracks (4) supported on the other side of the said ground plane and electromagnetically coupled with the slots (3). One of the ends of each feeding track (4) is input/output port (5) of the antenna element and the other end is disposed after the slot (3), so as the feeding tracks (4) to cross the slots (3). A compensating capacitive element (6) couples the ends of the feeding tracks (4) laid after the slots (3).
