Hexad loop (H-loop) antenna in front of 60/spl deg/ corner reflector for EMC measurement

Abstract

A newly developed EMC (electromagnetic compatibility) antenna is proposed in this paper which can simulate a highly directive standard EM (electromagnetic) wave. The proposed antenna can be made by placing one-sixth of conducting loop-wire (H-loop) in front of a 60/spl deg/ degree corner reflector. The mathematical model of such a quasi-shield probe called the H-loop is developed. The developed antenna parameters have been compared with those of the existing quarter loop antenna and a complete loop antenna. The designed H-loop antenna has been constructed and the radiation pattern of the antenna is measured to compare the theoretical radiation pattern. Comparison shows a very good agreement with the theoretical pattern.
