Abstract
A dual offset reflector system is disclosed. The system comprises a main reflector, a subreflector, a first gimbal mechanism for positioning of the subreflector. The system includes at least two feeds for receiving beams from the main reflector and the subreflector. One of the feds is at a focal point of the system and the other beam is displaced from the focal point. Accordingly, a simple solution to restore antenna gain reduction and avoid beam distortion due to the scan loss for a reflector system is provided that utilizes multiple feeds at different frequencies and polarizations. By placing the feeds at focal point trajectory of the subreflector whose positioning is controlled by a gimbal mechanism, a system is provided that minimizes distant and scan loss in a dual reflector system. The gimbal mechanism positions the subreflector so that a desired feed is in the focal point of the subreflector.
