Design and Realization of Q/W -band Beacons System for GEO Communication Satellite

Abstract

The Q-band and W-band of electromagnetic wave have broadband which have significant advantages for satellite-ground communication. However, it also encounters many difficulties and challenges by adapting Q-band and W-band to communication in technique, such as propagation influenced by climate. To deal with the problems, the development of a Q/W dual-band beacon system is introduced which is installed on board of a GEO communication satellite. The beacon system is used to test the characterization of Q-band and W-band satellite-ground propagation channel, including research on atmospheric attenuation and rainfall attenuation.
