Abstract
A point-to-multipoint communications system. The system uses an antenna to generate a single beam having independently steerable, narrow lobes. The phase array and amplitude array distributions used to form the lobes are controlled so that the lobes track and provide full duplex communication links with two or more RF terminals in two or more remote locations. In certain embodiments the dual lobe beam is generated from a fixed, ground-based location, and in other embodiments the single beam is generated from an airborne mobile platform, a mobile land vehicle, or a marine vessel. The various embodiments all enable one, two or more full duplex communication links to be established and maintained with a single beam.
