摘要： A double reflector antenna system has a polarization rotating main reflector which is symmetrical, a polarization dependent subreflector which is symmetrical, and a feeder arranged with its aperture between the main reflector and the subreflector to deliver energy to or receive energy from the subreflector, the aperture being in a plane perpendicular to the symmetry axis of the two reflectors and having an oval shape facing the subreflector.
