摘要： 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.

摘要： A multiple-feed antenna system includes a first feed configured to communicate signals in a first frequency range of a plurality of frequency ranges and a second feed configured to communicate signals in a second frequency range of the plurality of frequency ranges. A subreflector assembly is configured to move among multiple positions that include a first position and a second position. When the subreflector assembly is in the first position, a first element of the subreflector assembly redirects a signal reflected by a primary reflector to the first feed. When the subreflector assembly is in the second position, a second element of the subreflector assembly redirects the signal reflected by the primary reflector to the second feed.
