摘要
Since the discovery of high temperature superconducting(HTS)materials in the 1980 s,HTS filters and motors have developed rapidly[1,2].The extremely low insertion loss and frequency selectivity of the HTS filter make it possible to greatly improve the signal receiving sensitivity and suppress interference noise.Therefore,it has great potential in aerospace application,satellite communications,mobile base stations,deep space exploration,radar,and other fields[3,4].
