Accurate fullwave analyses of microstrip dipoles on multi-layer substrates with generalized anisotropic permittivity and permeability have been developed. The solution to the problem of microstrip dipoles onin gyrotropic substrates has been obtained. The potential of electronically shaped, scanned, and gain enhanced element factors with ferrite substrates has been theoretically demonstrated. The scattering and radiation problems were solved. The use of biased ferrite substrates to simultaneously reduce RCS and preserve antenna in- band gain has also been described. Infinite phased arrays of microstrip dipoles and probe-fed patches on general anisotropic multi-layer substrates have been analyzed. All the solutions involve the dyadic Greens function for the anisotropic layered structure and the application of the method of moments to an electric field integral equation....
