Abstract
A compact phased array fed dual reflector antenna system. The antenna system includes a parabolic main reflector, an elliptical sub-reflector, and a phased feed array. The focal point of the parabolic main reflector is located on the elliptical surface of the sub-reflector. A first elliptical focal point of the sub-reflector is located on the parabolic surface of the main reflector while the second elliptical focal point is located on the radiating surface of the feed array.
