ABSTRACT:
A novel single-aperture antenna system for producing multiple closely spaced or overlapping beams. The antenna system has multiple feeds for radiating energy, and a hyperboloidal or ellipsoidal main reflector responsive to the radiated energy for forming multiple beams. The main reflector is configured to form one beam for each of the multiple feeds in the antenna system.
