Abstract
A multiband satellite communication antenna system includes a primary reflector and one or more movable subreflectors. A system with one subreflector operates at a first band when the subreflector is in a deployed position and reflects energy between a first feed and the primary antenna. When the subreflector is at a second, stowed, position, the primary reflector operates directly into a second feed. A communication antenna system with two subreflectors can operate at three bands under the conditions of having either both subreflectors stowed; the first subreflector deployed and the second subreflector stowed; or both subreflectors deployed.
