Abstract :
The effects of solar panel scattering on a Ku-Band reflector antenna performance are analysed. It is shown from computation and experiment that the solar panel scattering interference causes mainlobe gain decrease and sidelobe gain increase on the sum patterns, as well as null position shift and null depth decrease on the difference patterns
