Rain Attenuation Prediction Models in Microwave and Millimeter Bands for Satellite Communication System: A Review

The progressively demand on satellite communication systems has consequently resulted in lower frequency bands getting more congested. The usage of frequency band beyond 10 GHz is in focus nowadays as a result of the rapid expansion of radio communication systems. However, Rain is the leading attenuation factor of different communication signal of frequencies beyond 10 GHz. Attenuation due to rain has a significant propagation effect that needs to be carefully considered in satellite communication system network. Rain attenuation predictions and rain rate are essential when planning microwave satellite communication links.  A review of the rain rate integration time and rain attenuation models for microwave and millimeter bands satellite system is presented.
