Method of Moments Solution for the Electric Currents on an Aperture-Fed, Stacked Patch Microstrip Antenna.

摘要

This study presents a method of moments solution for the surface currents and charge distributions on an aperture-fed, stacked patch antenna. To make the solution independent of the antenna excitation technique, an aperture magnetic current distribution is assumed, and the spatial Green's functions of the antenna are used to calculate the tangential fields on the antenna patches and coefficients for a finite series expression of the surface currents and charge densities. The Green's functions of the antenna are modeled with polynomials that are a function of the radial distance separating observer and source locations. The method of moments solution is implemented using FORTRAN 77 and requires no external software support. The numerical techniques, algorithms, and complete software functional descriptions are also included. Theses (RH)
