摘要：
This work explores the effects of a compact, superconducting C-shaped patch printed on uniaxial anisotropic substrate, utilizing two uniaxial substrate materials: boron nitride and magnesium fluoride. This study employed the superconducting material BSCCO (2212 BSCCO crystal), with a critical temperature of 95 K. Using the hybrid cavity model, we identified and extracted two key parameters: the resonance frequency of conductive elements and the superconducting resonance frequency. We analyzed the impact of the operating temperature on the resonant frequency of a C-shaped superconductivity microstrip antenna, as well as the effect of the uniaxial substrate material and its thickness on the surface resistance and surface reactance. The results showed that temperature significantly affects the resonant frequency of the compact antenna. Our research highlighted the importance of selecting the correct operating temperature for a superconducting microstrip antenna to ensure optimal performance in compact microstrip antenna designs.
