The moment method technique has been improved to in- vestigate the scattering properties of high Tc superconducting circular antennas with anisotropic substrate in multi-layered conflguration. In this method, the electric fleld integral equation for a current element on a grounded dielectric slab of inflnite extent was developed by basis functions involving Chebyshev polynomials. An improved analytical model is presented taking into account anisotropic substrate, super- conducting material for the circular patch and multilayered structure. To validate the theoretical results, an experimental study has been performed for a perfectly conducting circular patch on a single layer, with and without air gap. Good agreements were obtained between our theory and measurements. Efiects of temperature and thickness
