This algorithm is proposed to handle arbitrary anisotropic dielectric media. By combining the FDTD approach with the material-independent perfectly matched-layer absorbers, the performance of a line-fed microstrip antenna patched on a general anisotropic dielectric substrate is developed. The scattering parameters of the antennas as a function of the rotation angle of the optical axis of the anisotropic substrate are presented.
