摘要
高温超导 (HTS)体由于具有较低的表面电阻 ,在天线应用中 ,它可以提高天线的效率。天线作为特殊的散射体 ,会将部分接收的入射场再辐射出去 ,而超导天线散射场的强度可以通过控制温度来进行控制 ,并且高温超导微带天线可以实现天线小型化 ,这就可以实现减缩天线雷达散射截面 (RCS)的目的。对高温超导线天线和微带贴片天线的分析结果证明了结论的可行性。
The high-temperature superconductors (HTS) bearing low surface resistance can be used to raise the efficiency of antenna. The scattering strength of HTS antenna can be controlled by the temperature change and the HTS microstrip patch can be designed with a much smaller size, so the radar cross section (RCS) of antenna may be reduced effectively. The simulation results for the HTS wire antenna and microstrip patch antenna were presented to prove the proposed ideas.
