Abstract :
The design objectives and electrical performance data of a circularly polarized offset reflector antenna for the illumination of the FRG are presented. The requirements are based on the WARC regulations settled for direct broadcasting satellites /1/. The antenna consists of an offset paraboloid reflector with an elliptical corrugated feedhorn with RF-sensor. Measured radiation pattern, gain figures and RF-sensor performance data are presented. Pattern degradations caused by reflector tilting for beam fine pointing and thermal deformations are considered.
