摘　　要：在液氦温度下，研究了工作频率为6．26GHz的Y系超导圆极化微带天线的传输系数S21及圆极化轴比随外加工磁场的变化．实验结果表明：在4．2K温度，外加磁场B≤1T时，其S21及圆极化轴比基本不随外加磁场的变化而改变．In this paper an HTS circular polarized microstrip antenna was prepared.Its working frequency is 6.26GHz.The DC magnetic field dependence of the transmission coefficient of the antenna at B≤1T and T= 4.2K was presented.The circular polarization property of the antenna was also measured.It is concluded that the transmission coefficient and circular polarization ratio hardly change with DC magnetic field up to 1T at 4.2K.
