This paper investigates the effect of reflector surface distortion on the antennaradiationpattern, and gives some reasonable criteria for reflector antenna structure design.
The antennaradiationpattern and antenna coupling or isolation as well as near electric field strength are measured by using anechoic chamber as the test site of ship model prediction.
