高温超导(HTS)无源微波器件，如滤波器和天线，是很有前途的器件。特别是，HTS过滤器可能在不久的将来成功上市。交叉耦合滤光片、环形滤光片和共面波导滤光片是减小滤光片尺寸的好选择。另一方面，可以被低温制冷器冷却的高温超导贴片天线也是一种很有前途的器件，因为它们比普通天线显示出更高的效率。本文研究了高温超导滤光片的设计过程和滤波特性，以及高温超导贴片天线的增益、方向性和冷却系统。
High-temperature superconducting (HTS) passive microwave devices, such as filters and antennas, are promising devices. In particular, HTS filters may be successfully marketed in the near future. Cross-coupled filters, ring filters, and coplanar waveguide filters are good options to reduce filter size. On the other hand, HTS patch antennas which can be cooled by a cryo-cooler are also promising devices as well, since they show higher efficiency than normal antennas. This paper examines the design process and filter properties of HTS filters as well as the gains, directivity, and cooling system of HTS patch antennas.
