Abstract
An antenna comprises a plurality of tiles forming an antenna plane, each of said tiles comprising a plurality of radiating elements. Each radiating element comprises a metallic upper patch disposed above a metallic lower patch, the two patches being separated by a layer insulating them electrically. The lower patch is fed with electric current. Each radiating element comprises a conducting frame disposed parallel to the antenna plane and framing the two patches of said element, the two so-called patches being coupled electromagnetically through the aperture of said frame whose body comprises a rear face of small cross section disposed on the side of the lower patch and a front face of larger cross section disposed on the side of the upper patch, so as to widen the angular scan field of a beam in a plane orthogonal to the antenna plane.
