Ka-BAND PROPAGATION RESEARCH USING ACTS
International Journal of Satellite Communications, 1996The congestion of the radio spectrum below about 18 GHz is causing a rush of interest in the 20/30- GHz band. Due to the shorter wavelength of these frequencies, the atmosphere, especially rain, greatly influences the transmission of signals between earth/space stations. The slant path effects in the Ka region of the radio spectrum are addressed and an
