Abstract:
A multiple-feed antenna system includes a primary reflector that directs signals along a primary RF signal path and a movable subreflector assembly. When the subreflector assembly is in a first position, a first subreflector element of the subreflector assembly redirects signals traveling along the primary RF signal path to a first RF signal path and a second subreflector element of the subreflector assembly does not intersect the primary RF signal path. When the subreflector assembly is in a second position, the second subreflector element redirects signals traveling along the primary RF signal path to a second RF signal path and the first subreflector element does not intersect the primary RF signal path. The antenna system includes a first feed of the antenna system intersects the first RF signal path, a second feed that intersects the second RF signal path, and an actuator that moves the subreflector assembly.
