Title: Steerable offset reflector antenna

Abstract: An antenna system that includes one or more antenna feed horns (30), where each feed horn (30) includes a plurality of micro-mechanical devices (38) positioned around the aperture (32) of the feed horn (30). The micro-mechanical devices (38) are linear motion devices that can be activated to extend a conductive surface (40) beyond the end of the feed horn (30). By selectively actuating groups of the micro-mechanical devices (38) to extend the conductive surfaces (40), the end of the feed horn (30) can be changed to provide different asymmetrical configurations, causing the beam direction to change accordingly. The micro-mechanical devices (38) can be any suitable mechanical device, such as MEMS devices or carbon nanotube artificial muscles.
