Abstract
An antenna system for producing a beam of radiated radio frequency energy. The system comprises an antenna feed, a shaped sub-reflector, and an unfurlable main reflector. The antenna feed supplies radiated radio frequency energy. The shaped sub-reflector receives the radiated radio frequency energy from the antenna feed. The unfurlable main reflector receives and reflects the radiated radio frequency energy from the shaped sub-reflector as a shaped beam having a predetermined shape. The sub-reflector has a configuration that shapes the beam reflected from the unfurlable main reflector to have the predetermined shape.
