Abstract :
Multibeam reflector antennas attract more interest nowadays with the ever increasing requirements of spaceborne. It features two sets of feeds located in the focal plane to generate two scanning beams. The twin-horn structure is employed to better receive remote sensing signals reflected. The far-field pattern of the reflector antenna illuminated by the measured twin-horn feed pattern is also obtained, and the simulation results match well with the design goals.
