Abstract
Deployable antenna systems for use on a spacecraft that is moveable from a stowed position to a deployed position. Two embodiments are disclosed that include one or two sets of main reflector assembly (and optional adjustment mechanism) and subreflectors. The antenna systems include a feed horn assembly fixedly attached to the spacecraft and a rotatable hinge attached to the spacecraft. A substantially rigid reflector support structure is attached to the hinge and rotates about a hinge axis. The main reflector assembly (and optional adjustment mechanism) is attached to a lower portion of the support structure and the subreflector is attached to an upper portion of the support structure. The subreflector has a fixed relation relative to the main reflector assembly and has a fixed relation relative to the feed horn assembly when the antenna system is in the deployed position so that the antenna systems generate predetermined beam coverage patterns.
