Simple analysis of anisotropic microstrip lines by a transform method

Abstract

For the TEM-mode investigation of microstrip lines on anisotropic substrates, a simple, but rigorous, transformation is introduced, which converts the anisotropic electrostatic field into an isotropic one with similar shape; the latter has been extensively analysed in the past. The transformation also applies to related anisotropic problems. Results for single and coupled lines are presented. Dispersion is briefly commented on.
