Abstract
Methods and systems for a multiple-feed antenna are described. The multiple-feed antenna includes a primary reflector that directs signals along a primary RF signal path and a subreflector assembly that rotates between a first position and a second position. 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. 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. The antenna system includes a first feed that intersects the first RF signal path, a second feed that intersects the second RF signal path, and an actuator that moves the subreflector assembly.
