Full-Wave Characterization of Open-End And Gap Discontinuities of Shielded Coplanar Striplines

摘要

In this work, we study the two discontinuities open-end and series gap in the coplanar striplines. New integral equations for the electrical field components are formulated, in the spectral domain, using an exact dyadic Green's function, applied to the coplanar stripline structure. The use of this type of Green's function, we permeate the consideration of the effects of the dielectric losses, surface waves excitation and space waves radiation on the propagation characteristics of the coplanar strip line and its two discontinuities. The resulting integral equation has been solved by the two-dimensional Galerkin's technique. The resulting matrix equation resolution we gives the S-parameters of the two studied discontinuities. Our results are compared to those of other approaches.
