✦ Synopsis

In this article an integral equation for a microstrip antenna on a finite ground plane is deri¨ed with the use of the reaction theory and the dyadic Green's function. The integral equation is sol¨ed with the use of the Galerkin method, and the current densities on the patch and the ground plane are obtained simultaneously. The far-field radiation pattern is e¨aluated from currents on the patch, on the ground plane, and on the polarization currents within the substrate. Results are presented for the case where the patch and ground plane are of same size. The results are compared with measured data and show ¨ery good agreement. ᮊ 1997
