RESUMO

The boundary value problem associated with the shielded microstrip-line structure is formulated in terms of a rigorous hybrid-mode representation, superposition of the TE and TM fields. The resulting equations are subsequently transformed, via the application of Galerkin¿s method in the spectral domain, to yield a characteristic equation for the dispersion properties of shielded microstrip lines. Among the advantages of the method are its simplicity and rapid convergence. A computer program for the parameters is presented, and numerical results are compared with some experimental results and with theoretical and empirical results presented by other authors. The behavior with the variation of the height of the top cover is also considered.
