Asymmetric microstrip lines on anisotropic substrates with material axes inclined in the transverse plane

Abstract : The frequency-dependent characteristics of shielded asymmetric microstrip lines on uniaxial and biaxial substrates are presented in this memorandum. The permittivity tensor of the supporting medium is assumed to have off-diagonal elements due to the misalignment between the waveguide coordinate system and that of the material. New data for the dispersive properties of the asymmetric structure are provided for frequencies up to 40 GHz.... Frequency- dependent characteristics, Biaxial substrates, Asymmetric microstrip.
