First Claim
Patent Images
1. An antenna element comprising:
- a ground plane having two substantially identical slots being disposed at right angles to each other and symmetrically crossing in respective midpoints thereof, a radiating patch disposed in a predetermined spaced relationship with and above the said ground plane, conductive feed tracks disposed below the said ground plane, having electromagnetical coupling with the said slots, each of said feed tracks having on one end thereof an input/output port of the antenna element and the opposite end thereof disposed after the said slots, so as the feed tracks pass under the corresponding one of said slots, characterized in that the said opposite ends of the said feed tracks are coupled by a compensative capacitive element.

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).
