Research on Serrations of Reflector Used in CATR

It is generally accepted that the design of reflector used in Compact Antenna Test Range (CATR) is a challenging job for a long time, especially for the design of its serrations. In order to solve the addressed problem above, this paper will mainly include four parts as (1) Choosing an appropriate algorithm in software to conduct simulation effectively under certain frequency. (2) Studying the scattering mechanism of the reflector's rim. (3) Comparing the quiet zone characteristics between reflectors with different serrations which are commonly used. (4) Offering guidance parameter configuration to obtain proper serrations. At last, we can come to the conclusion that the theory analysis agrees with the simulation results.
