Abstract
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.
本研究利用氮化硼和氟化镁两种单轴基底材料，探索了在单轴各向异性基底上印刷紧凑型超导 C 形贴片的效果。这项研究采用了临界温度为 95 K 的超导材料 BSCCO（2212 BSCCO 晶体）。利用混合空腔模型，我们确定并提取了两个关键参数：导电元件的共振频率和超导共振频率。我们分析了工作温度对 C 型超导微带天线谐振频率的影响，以及单轴衬底材料及其厚度对表面电阻和表面电抗的影响。结果表明，温度对紧凑型天线的谐振频率有很大影响。我们的研究强调了为超导微带天线选择正确工作温度的重要性，以确保紧凑型微带天线设计的最佳性能。
