The Effects of Rain on Millimeter Wave Communication for Tropical Region

The effects of rain on millimeter wave communication are investigated in the present study. Propagation of very short pulses at mm wave band has been discussed. Specific attenuation has been computed at different mm wave frequencies and its variation as a function of rain rate and frequencies have been assessed. The variation of rain attenuation over terrestrial link as a function of path length, frequency and rain rate has been examined. A comparison between rain attenuation along terrestrial path and earth space path has been made at mm wave band.
