Derivation of potential Green functions for ungrounded dielectric slab and its application in full wave analysis of PMAs

Abstract

In this paper, spatial domain potential Green’s functions of a horizontal electric dipole lying on an ungrounded dielectric slab is derived. The full wave technique using mixed potential integral equation (MPIE), involving the derived potential Green’s functions and method of moment (MoM), is used to calculate input impedance as well as reflection coefficient of printed monopole antennas (PMAs). The performance of rectangular and F-shaped PMAs is evaluated using the earlier mentioned full wave technique. The computed results for the input impedance and reflection coefficient of rectangular PMA are verified with high-frequency structure simulator (HFSS) results. Further, reflection coefficient of F-shaped PMA is computed using MPIE–MoM which is verified by HFSS simulation and experimental results.
