Abstract

A hybrid technique of the finite-element method and the method of moments (FEM/MoM) is used to analyze the effects of multilayered superstrates on cavity-backed slot (CBS) antennas. The spectral-domain approach is used to compute the MoM admittance matrix. An asymptotic extraction technique is applied to improve the computational efficiency of the convolutional integrals. Effects on the input impedance, efficiency, gain, and radiation patterns are presented for different antennas. The numerical results are validated with measurements and published data.
