Abstract

The reflector antenna and feed system of an 11-m diameter earth-station that operates in circular polarisation at X-band is described. The reflector-optics are required to have high G/T, sidelobes that satisfy the CCIR recommendation and low mismatch at the feed. The feed system is required to have high isolation between the transmit and receive ports (> 40 dB) at the centre of the band. This isolation is achieved by minimising reflections from all components forward of the polariser. The measured performance of the reflector and feed system is described.
