High performance C/Ku band dual polarization feed system for 25 meters Cassegrain reflector antenna

This paper presents the development of the dual band C/Ku feed system based on corrugated horn antenna with dielectric rod. The feed is designed for 25 meters diameter Cassegrain reflector antenna. The full-wave optimization results of the system components including turnstile junction, diplexer, polarizer, OMTs are provided. Measured VSWR results of the system are below 1.5, which agrees with simulations.
