Estimation of Antenna Factor of reduced-height loaded wire antennas

This paper presents the initial investigation on the performance of different loaded wire antennas (e.g. inverted L, T, I and C-shaped antennas) as electromagnetic interference (EMI) sensors. The performance of these loaded antennas as EMI sensors is described in terms of the Antenna Factor for the desired and cross-polarized component of incident electric field. The Method of Moments with Pulse basis function and Point-matching technique has been used to evaluate the current distribution on the antenna surface and hence the Antenna Factor. The results have been compared with the data achieved using a commercial software - CST-Microwave Studio.
