ABSTRACT OF THE DISCLOSURE An antenna system comprises a reflector which is a part of a paraboloid of revolution or parabolic cylinder, a primary radiator for clockwise circularly polarized wave, and a primary radiator for counterclockwise circularly polarized wave. The reflector is of geometrically asymmetrical shape to effect different reflection properties for clockwise and counterclockwise circular polarizations. The primary radiators are fixed at two different positions in the vicinity of the focus of the paraboloid reflector. Both clockwise and counterclockwise circularly polarized waves can be transmitted from and received by a single reflector.
