Measuring Complex for Studying Directional Characteristics of Antennas of Satellite Earth Stations

The results of the development of a measuring complex for studying the directional characteristics of antennas of earth stations of satellite communications in the Q-band are presented. A block diagram of the measuring complex has been developed and its appearance is shown. The first results of experimental studies of a satellite earth station antenna with a diameter of 0.5 m are presented. It is a two-mirror design of the Cassegrain scheme with a parabolic reflector. The measurements were made with a spherical scanner using the spiral scanning method.
