Multi-Conductor Spectral Domain Analysis of the Mutual Coupling Between Printed Dipoles Embedded in Stratified Uniaxial Anisotropic Dielectrics

New multi-conductor spectral domain immittance functions are derived for modeling the mutual coupling between printed dipoles of arbitrary length embedded in stratified uniaxially anisotropic dielectrics. The coefficients for the newly derived multi-conductor spectral domain immittance functions are closed-form trigonometric functions, which shows that these new expressions are as simple as the single-conductor spectral domain immittance functions derived in previously published literature. Many different configurations of printed dipoles in stratified uniaxially anisotropic dielectrics are investigated for the first time. In particular, the effects of the thickness and the anisotropy ratio of each layer on the mutual coupling of the printed dipoles are determined. The numerical results from the new spectral domain immittance functions are compared to numerical results from commercial software and published literature with good agreement in all cases.
