Abstract

The convergence of SEMN (surface equivalence principle and multiple network theory) method in the computation of the input impedance of a probe-fed finite rectangular microstrip patch antenna is studied. Comparing the electric and magnetic field integral equation (EFIE and MFIE) formulations of the SEMN method, it is shown that the MFIE formulation has a better convergence criterion. Also, it is shown that lower size segments are required when the substrate or ground plane are extended beyond the patch.
