Abstract:
1. A multi-satellite access antenna system for accessing a plurality of satellites having different polarization characteristics, comprising: a plurality of first subarray antennas disposed on a first surface of the antenna system, each first subarray antenna having circular polarization radiation means, having both left handed and right handed polarization electric characteristics relative to each other; a plurality of second subarray antennas disposed on a second surface of the antenna system, each second subarray antenna having linear polarization radiation means having both vertical and horizontal polarization electrical characteristics relative to each other, wherein the first and second surfaces are, segregated from each other on separate opposite sides of the antenna system; and an active module interposed between the first and second subarray antennas wherein the active module is operatively configured to substantially correct a phase difference artifact of a received satellite signal brought about by an elevation angle of anyone of the subarray antennas when inputting the received satellite signal.
