Electromagnetic Interference (EMI) is becoming a crucial issue in the era of modern electronic systems. For EMI measurement, it is required to place a sensor to receive the radiation from the equipment in a suitable test environment. The performance of the sensor depends on its Antenna Factor, which is the ratio of the incident electric field on the antenna surface to the received voltage at the load end across 50 Ω resistance. FDTD is one of the efficient numerical techniques to solve radiation and scattering problem in any environments. To the best of the knowledge of the authors no literature is available where FDTD is used to evaluate the Antenna Factor. Here, in this work we applied FDTD to predict the performance of dipole antenna when it is used as a EMI sensor. The results presented here for free space environment are compared with published results.
