Miniaturization of microstrip patch antennas using superconducting thin films at the high temperature of transition

Working near to the high temperature of transition of a superconducting thin film material leads to important reductions in the size of a microstrip patch antenna. A superconducting film over an isotropic substrate is taken and different values of resonant frequencies for different patch thicknesses are calculated and compared with the resonant frequency of a normal conducting patch antenna posed over the same substrate. The difference in frequency of the same sized patchs leads to reduce the size of the superconducting patch antenna to have the same frequency as the normal conducting one.
