Abstract
The invention is related to an aperture antenna element (1) comprising a ground plane, an aperture feed (3) and a reflector (2). In accordance with the invention, the at least one aperture (3) is provided directly on said ground plane, wherein the ground plane is also the reflector (2). In accordance with the invention, the aperture feed (4) is separated from said ground plane. The invention also relates to an aperture antenna including such aperture antenna elements.
