Abstract
An antenna system for producing selectively reconfigurable antenna beam coverage patterns suitable for use in on an earth orbiting spacecraft is described. The system comprises a main reflector and a feed element with a subreflector module on which are disposed one or more subreflectors. The subreflector module is selectably positionable such that any one of the subreflectors may be disposed such that it is illuminated by the feed element and illuminates the main reflector. Each of the subreflectors has a shaped surface corresponding to a desired antenna beam coverage beam pattern. By appropriate selection from among the plurality of subreflectors, any one of a plurality of antenna beam coverage patterns can by provided with a single feed element and single main reflector.
