The antenna has a cavity (24) with an assembly including a pair of semi-reflecting plane metallic mirror grids (23, 26) that are perpendicular to an axis of the antenna. The assembly has two zones (25, 29) of active material layer placed adjacent to the respective mirror grids. The layers are controlled by respective polarization zones defined by metallic patterned layers that are subjected to an electric control potential. - The patterns are juxtaposed with the layers and are directly fabricated on the surface of the active layer.
