ABSTRACT:
A mobile tracking antenna for microwave signals from a satellite or distant transmitter includes a micro- electromechanical system produced by semiconductor processing. Specifically several micro faceted reflector segments have their facets selectively controlled by a feedback control system and reflects the signal onto a four sector horn which then by error signals actuates electrostatic positioning means on the micro facets to center the signal on the optimum receiving portion of the horn. Each segment covers a portion of the 360.degree. receiving spectrum. The particular segment is selected by a maximum signal being received.
