Inclined GEO satellite communication system with deployable phased array antennas

Abstract

We propose a new satellite communication system using inclined GEO satellites which mount deployable phased array antennas. An example is shown of the inclined GEO locus. In this system, the satellite illuminates multiple beams to a certain area from a high elevation angle, so that the degradation due to shadowing effect can be reduced. When large aperture phased array antennas are used for satellite antennas, high communication capacity can be attained using small size portable terminals as earth stations. The system configuration of this system is shown. A large aperture phased array antenna is used for the satellite antenna, so as to achieve low power portable terminal.
