Abstract

A superconducting material of the YBCO family is considered. It is printed over a uniaxial anisotropic substrate: the Saphire material. The resonant frequency and the bandwidth are calculated using different patch thicknesses at temperatures very close to the high temperature of transition. The numerical results are compared with those of a conductor patch and are found that they are better than the conductor´s one.
