Abstract
A reflector array antenna with cross-polarization compensation including at least one radiating element having an etched pattern dissymmetric with respect to at least one direction X and/or Y of the plane XY of the radiating element, the dissymmetry of the pattern of the radiating element being calculated individually on the basis of a radiating element of the same symmetric pattern along the two directions X and Y, so as to engender a reflected wave having a controlled depolarization which opposes a depolarization, engendered in a plane normal to a direction of propagation, by the reflector array illuminated by a primary source.
