Abstract
Monopole antennas are usually used for measurement of the shielding effectiveness of metallic enclosures. This paper presents an accurate numerical modeling for monopole antennas attached in shielded enclosures with apertures. The electric field integral equation (EFIE) is formulated for the induced currents on both the monopoles and enclosure. The precorrected-FFT accelerated method of moments (pFFT-MoM) is used to solve the integral equation and the incomplete LU (ILU) preconditioner is applied to speed up the convergence of the equation. Compared with existing methods, the model presented in this paper considers the mutual coupling between the monopoles and shielded enclosure. Therefore, it is a better approximation to the actual measurement geometry.
