Abstract

A multiple beam space antenna system for facilitating communications between a satellite switch (100) and a plurality of earth-based stations (1,a,b,) is shown. The antenna is deployed after the satellite is in orbit by inflation of a raft-type supporting structure which contains a number of antenna horns (80). These antenna horns are oriented in substantially concentric circular groups (A-D) about a centrally located antenna horn (80). Each of the antenna beams projects an area on the earth. Each of the areas (a,b) of the beams are contiguous. As a result, one large area is subdivided into many smaller areas to facilitate communications. In addition, a lens (FIG. 7C and 7D) may be employed to focus the beams of the horn antennas.
