Abstract :
The computer analysis of dual-offset reflector antennas fed by a circular corrugated horn, using an accurate feed model, is described. Near-field, thermal-paint, and carbon-fiber-reinforced plastic (CFRP)-structure effects are included in order to simulate a realistic design scenario and predict their impact on the radiation characteristics. The theoretical results have been verified by experiment for a near-field illuminated offset Gregory antenna
