Various types of transmission lines with anisotropic substrates have been investigated for use in microwave- and millimeter-wave integrated circuits. These include single and coupled striplines, slot lines, and coplanar-type transmission lines. The coplanar-type transmission lines CTLs are promising because of their easy adaptation to shunt element connections. The application of coupled coplanar-type transmission lines. C-CTL have been studied based on the quasistatic and hybrid-mode formulations and accurate numerical values are available for the cases with isotropic andor anisotropic substrates. However, most of them assume the structural symmetry. The theoretical approach for the asymmetrical version is available only for the propagation constant of the case with a single isotropic substrate. This paper presents the analytical method for the general structure of asymmetrical coupled coplanar-type transmission lines with an anisotropic substrate. This method includes both the hybrid-mode and the quasistatic formulations and is useful for accurately computing the characteristics impedances as well as propagation constants of various types of asymmetrical coupled coplanar-type transmission lines.
