Abstract
A phased array satellite communication (SATCOM) system for ground stations receives information signals and a beam from a satellite and autonomously steers communication signals by phase information toward a satellite extracted from the received satellite beam. The new phased array eliminates the need for phase shifters to control a beam. The new phased array satellite communications system avoids delay in digital signal processing or feedback systems to find satellite locations, enabling autonomous real-time electronic beam steering with no delay. The new system is also used to handle signals from and to multiple satellites simultaneously. The new system is useful in other applications where an enhanced point-to-point communication link is required.
