ABSTRACT:
The present invention provides a patch antenna comprising a patch spaced from a ground plane and two L-shaped feed probes. Each feed probe is connected to a respective input port and has a portion extending parallel to the patch. The antenna further includes at least two walls extending from the ground plane towards the patch. The walls are positioned between the L-shaped feed probes so as to permit direct propagation between the input ports and also to create indirect diffraction paths between the input ports that serve to cancel at least a part of said direct propagation.
