中文摘要：

从两个方面分析了高温超导带材在水下超低频（30-300Hz）天线中的应用。首先提出了YBCO高温超导带材制做的水下发射天线模型;然后采用超导线圈以减小磁场环接收天线热噪声（ENF）,提高接收灵敏度。最后结合52Hz,102Hz,202Hz频段超导带材的交流损耗、超导磁场环天线ENF等测试结果,得出高温超导带材的应用可提升水下超低频天线系统性能。

英文摘要：

Two parts on the application of SLF（30-300Hz） undersea HTS antenna were analyzed.First we proposed an undersea transmitting antenna system especially contains two superconducting YBCO tuning solenoids to merit the reactance matching of the electronically small antenna.Then we analyzed a magnetic coils receiving antenna made of HTS tapes to decrease its thermal noise and increase the sensitivity.Third,we reformed the undersea transmitting antenna by adding the HTS magnetic receiving antenna to fulfill its all-around receiving purpose.By means of modeling analysis and AC power loss measuring experiment,a conclusion was drawn that YBCO tape play an excellent role in reducing the ohmic conductor loss（compared with copper or aluminum） and increasing the signal inception efficiency in SLF band.A conclusion was drawn that HTS strip is beneficial to promote the comprehensive performance of undersea SLF antenna system.
