Current distribution of a printed dipole with arbitrary length embedded in layered uniaxial anisotropic dielectrics

The current distribution of a printed dipole with arbitrary length embedded in several layers of anisotropic dielectrics is evaluated using the spectral domain immittance functions. In particular, the currents on a printed dipole on a single anisotropic layer and in three anisotropic layers are determined. A good comparison between the isotropic cases, commercial software and published literature is observed. Finally, general comments are made on how each component of the anisotropic permittivity affects the current distribution of the dipole.
