Investigation of the Directional Characteristics of the Antenna of the Satellite Earth Station Using the Spiral Scanning Method

Abstract

Results of earth station antenna experimental studies of satellite communication were shown. This antenna looks like two-mirror construction designed by Cassegrain circuit with parabolic reflector, which diameter is 1.2 m. This results made with help of spherical scanner by spiral scanning method. Antenna directional patterns were constructed. Deviation reasons of the measured directional characteristics from the calculated ones were analyzed
