<p>New spectral domain immittance functions based on Hertz vector potentials were derived to study the resonant frequency, input impedance and mutual coupling of printed dipoles in the presence of stratified uniaxially anisotropic dielectrics. In this study the current on each dipole was not assumed but was solved for using the moment method. This differs from all of the previous printed dipole research associated with anisotropic dielectrics because in previous work the printed dipoles were assumed to be Hertzian (i.e., constant current) or had an assumed sinusoidal current distribution. Original results show that the mutual coupling usually can be reduced by placing an anisotropic layer above both printed dipoles. In particular, it is determined that the permittivity in the direction of the optical axis below the dipoles could be used to design a specific resonant frequency of a given dipole while the permittivity orthogonal to the optical axis in the layer above the dipoles could be used to control mutual coupling. This is very important knowledge to have as a designer, especially for array applications. Computed results are compared to measurements, published literature and commercial software and are shown to have good agreement in all cases.</p>
