Abstract

Spectral domain analysis is used to study the propagation characteristics of grounded slotlines and edge-coupled microstrip lines on biaxial substrates. An expression is derived for the Green´s function. The expression is valid for substrates simultaneously specified by both their permittivity and permeability tensors. The behavior of the normalized wavelength, index of refraction, and propagation constant is examined in detail with respect to different linewidth/substrate-thickness ratios as well as the material parameters. Numerical data are tabulated with respect to different parameters for frequencies up to 40.0 GHz for both 0 degrees and 90 degrees rotations of the permittivity tensor.<>
