高温超导（ ＨＴＳ） 材料具有接近于无耗的特性，利用它可以构成高质量的微波谐振器、滤波器、多工器和天线等。它们可大大地改善微波系统的性能。本文综述了若干ＨＴＳ 微波无源器件及其应用的进展。已取得的研究成果表明，利用ＨＴＳ 薄膜的实用的微波电路及系统正在变为现实，其商用及军用预期在不远的将来将付诸实现 High-temperature superconducting (HTS) materials have nearly zero-loss characteristics, which can be used to form high-quality microwave resonators, filters, multiplexers and antennas. They can greatly improve the performance of microwave systems. This article reviews several HTS microwave passive devices and their applications. The research results obtained show that practical microwave circuits and systems using HTS thin films are becoming a reality and that their commercial and military applications are expected to be realized in the near future
