  • The reflector antenna distortion model is built by exploding test results. The radiation characteristics of a kind of distorted shaped reflector antenna are computed by using PO and PTD method, and the radiation characteristics of the reflector antenna with holes on the surface are also computed. The simulation results show that because of the local distortion of the reflector the radiation patterns become degraded. The sidelobe level in the azimuth plane becomes higher as the distortion area becomes bigger. It can be seen that the sidelobe level in the azimuth plane also increases because of the reflector perforated with holes on the surface.
