The goal is to demonstrate prototype active oscillator solar cell array antenna modules capable of beam steering based on multi-junction GaAs solar cell and oscillator antenna technologies. The beam forming circuitry and radiating elements are located on one surface of the substrate, and the solar cells on the opposite side. An integrated active oscillator with a solar cell array will potentially provide for a self-powered communications system. The proposed system will enable the development of low-cost, lightweight satellites with high directivity communication links for Flexible Access Networks.
