Abstract:
1. A reflector array antenna with cross-polarization compensation comprising a reflector array consisting of a plurality of elementary radiating elements regularly distributed and forming a reflecting surface; and a primary source intended to illuminate the reflector array; wherein the reflector array having a radiation diagram according to two orthogonal principal polarizations in a chosen direction of propagation with a chosen phase law; each elementary radiating element has been produced in planar technology and comprises an etched pattern consisting of at least one metallic patch and/or of at least one radiating slot, at least one radiating element of the reflector array comprises an etched pattern having a dissymmetric geometric shape with respect to at least one of the directions X and/or Y of the plane XY of the radiating element, the dissymmetry of the etched pattern of the radiating element consisting of an angular inclination of at least one side, respectively of at least one branch, of the geometric shape of the etched pattern with respect to the directions X and/or Y of the plane of the radiating element.
