Abstract
A steerable antenna comprises a steerable main reflector and a stationary feed assembly and subreflector assembly configured in a side-fed configuration where the feed assembly is to a side of both the main reflector and the subreflector. The main reflector, subreflector and feed assembly together produce an antenna beam which is directed in a preselected direction by the main reflector. A gimbal is coupled to the main reflector for positioning the main reflector and scanning the antenna beam over a preselected coverage area while the feed assembly and subreflector remain substantially stationary.
