ABSTRACT:
An antenna system includes an antenna feed aligned with a subreflector and a main reflector. The subreflector has a concave surface defining a vertex. A main reflector having a concave surface is aligned with the subreflector to define an antenna focal area at the vertex of the subreflector. The antenna feed may be a phased array or fixed antenna feed. The antenna system may further include a controller cooperating with the phased array antenna feed for beamsteering or beamforming. The controller may cooperate with the phased array antenna feed to define and steer multiple beams, at different frequencies, for example.
