Abstract
In this work, an efficient algorithm to rigorously derive the spectral-domain impedance dyadic Green's function for patch antennas and (M)MIC on general complex anisotropic substrates is developed. The main advantage of the applied technique is that it provides closed-form expressions for transverse propagation constants and related immittances in the spectral domain and, therefore, allows the following parameters and structures to be taken into account: dielectric and magnetic losses of anisotropic media, alternative directions for magnetic bias, the finite metallization thickness of conventional conductors and superconductors including their losses, microstrip, multiconductor interconnects, coplanar-type structures, patch antenna and feed network. The theory is verified by comparison with previously published data. The flexibility is demonstrated for both superconductor and conventional conductor antennas and (M)MIC structures.
