Abstract :
Space communications systems operating in the bands above 10 GHz (e.g. 12 to 44 GHz) are considered. An overview of the major propagation problems associated with satellite communications is presented, and the impact of these factors on the design and performance of satellite systems is described. Gaseous attenuation, attenuation by rain, clouds, fog, snow, and ice, depolarization, radio noise, angle-of-arrival variations, bandwidth decoherence, and antenna gain degradation are discussed
