Abstract:
A finite-element formulation for the analysis of shielded lossy planar transmission lines is presented. The formulation determines the propagation characteristics of a planar transmission line and avoids spurious non-physical modes with non-zero divergence by requiring the field to be divergenceless. Singularities in the field at perfectly conducting corners are accounted for by using singular basis functions. In addition, a set of entire-domain basis functions are developed to reduce the number of unknowns. A quasi-TEM formulation is also presented to provide a comparison with the full-wave analysis. Numerical results are provided to characterize the propagation characteristics of a microstrip transmission line. In particular, their dependence on the thickness of the microstrip and losses in the substrate is examined. In addition, the propagation characteristics of symmetric coupled microstrip transmission lines of finite thickness and the use of artificial magnetic side walls with stripline geometries are analyzed.
