Development of a fractional loop antenna for EMC measurement

A newly developed EMC (electromagnetic compatibility) antenna is proposed in this paper which can simulate highly directive standard EM (electromagnetic) waves. The proposed antenna can be made by placing a one-sixth of conducting loop-wire (H-loop) in front of a 60° degree corner reflector. The mathematical model of such a quasi-shield probe called an H-loop is developed. The characteristics of this antenna have been compared with those of the existing quarter loop antenna and a complete loop antenna. The input impedance of the developed antenna is computed from the network representation of the H-loop antenna
