Abstract
A reflector antenna consisting of a conventional parabolic main reflector with a couple of symmetric shaped subreflectors is presented for receiving signals coming from two satellites with a significant angular separation in the geostationary orbit. The phase aberration due to a scanning angle of lens of beamwidths is efficiently corrected by the adequate shaping of the subreflector surfaces.
