Abstract

Full-wave analysis of a gap is carried out using Galerkin's method in the Fourier transform domain (FTD). In the formulation of the problem, we con-sider two types of resonators. The analysis is carried our for both electric and magnetic walls at the planes of symmetry. The equivalent length al. and Alm for electric and magnetic walls respectively. are determined prom the respective resonance frequencies of resonators. From Ale and Alm the discontinuity capacitances of the Pi- equivalent circuits are determined. The equivalent circuit of a microstrip gap is calculated for different gap spacing.
