近接放射イミュニティ試験用TEMホーンアンテナのインパルス波励振によるアンテナ開口面の過渡磁界分布

抄録

Assuming the close proximity radio frequency immunity test using impulsive electromagnetic waves, the validity of an exponentially-tapered TEM horn antenna as a radiator was examined. In this paper, the transient magnetic field distribution at the aperture of the antenna due to impulse wave excitation was measured in time domain. As a result, the uniformity of the transient magnetic-field distribution almost agreed with the measured result in frequency domain.
