Abstract
A semiempirical model is proposed for propagation parameters of high-T -C superconducting (HTS) coupled microstrip lines taking into account anisotropic dielectric permittivity of sapphire substrate and its temp erature dependence. The nonhomogeneous current distribution in a cross -section of the lines is considered for attenuation coefficient calcul ation. The current density distribution in the coupled strips and in t he ground plane is found for the even and odd modes. The model is veri fied by a comparison with full-wave analysis results and experimental investigations of coupled microstrip line HTS resonators. (C) 1998 Joh n Wiley & Sons, Inc.
