ABSTRACT:
A planar printed-circuited antenna for the transmission and/or reception of microwave signals has a first conductive element or patch substantially parallel to a ground plane, a first dielectric substrate separating the first patch from the ground plane, supply structure for the antenna, and at least one second patch which substantially identical to the first patch. The second patch is superimposed on the first patch and is substantially parallel to the ground plane. A second dielectric substrate separates the first and second patches, and at least one first short-circuit connects the first and second patches to each other. According to the invention, at least one of the first and second patches includes at least one slot.
