On the Problems of EMC Test Site and EMC Antennas

EMC 측정 시험장과 EMC 안테나에 관한 문제점

One of the most difficult and important problems associated with radiated electromagnetic emissions from digital devices are the determination of antenna factor and site acceptability of an open area test site. This paper presents the problems of the open area test site and EMC antennas far measuring electromagnetic interferences radiated from the equipements. It seems desirable that the antenna factor of EMC antennas be revised to the antenna factor with zero reflection presented in this paper for accurate measurements.
