Measurement of wet antenna effects on microwave propagation-an analytical approach

Losses due to water being in or on the surface of the radomes or the parabolic reflector and on the feed window of antennas occur during rain. One minute rainfall rate and corresponding rain attenuation data at 15, 23, 26 and 38 GHz bands were collected at UTM Skudai campus for a one year period. In order to separate wet antenna loss from the propagation measurement, an analytical approach has been proposed and the results are presented.
