The open-end resonator in suspended substrate transmission line was analyzed in terms of two open-end discontinuities on a line segment. A procedure for computing the resonant frequency and constant of propagation was demonstrated using a full wave analysis. The fringing capacitance was computed using an equivalent length extension model and a transmission line circuit model. The characteristic equation was derived using Galerkin's method applied in the Fourier transform domain. The calculation has been carried out in two increasing orders of approximation, and the results compared. The discontinuity capacitance dielectric constants. The dispersive propagation constant of suspended substrate line was also calculated by the Galerkin method.
