TWO-WAY COMMUNICATION SYSTEM UTILIZING SMALL C-BAND ANTENNA FOR DOWNLINK AND L-BAND FOR UPLINK

摘要

A low data rate L-band transmitter and antenna is combined with a high data rate C-band receiver and antenna link to a C-band transmitter and an L-band receiver on a geosynchronous orbiting satellite. The receive antenna comprises a three parabolic dish design receiving vertical and horizontal polarizations from the satellite. The L-band transmit antenna is a wire Yagi antenna mounted between dishes.
