Abstract

Electromagnetic Interference (EMI) is becoming a crucial issue in the era of modern electronic systems. For frequency domain EMI measurements, an antenna with wideband performance in amplitude is desired but for transient field measurements, an antenna with wide-band performance both in amplitude and in phase is desired. The complex antenna factor (CAF) is an appropriate characteristic of such an antenna, which is the ratio of the incident electric field on the antenna surface to the received voltage at the 50 Ω load resistance. In this work, FDTD is applied to predict the performance of wire antenna when it is used as a sensor to measure the Electromagnetic field. The results presented here are compared with the published results.
