| 摘 要： | 分析了各向异性衬底上的高温超导微带天线特性.选取两种典型的高温超导各向异性介质--GaNdAlO3和SrLaAlO4作为高温超导微带天线的衬底,采用各向异性媒质中的谱域矩量法,对微带天线的输入阻抗和辐射效率进行了计算.计算和分析结果表明,高温超导衬底的各向异性特性会影响高温超导微带天线的性能,而且这种影响因衬底而异,同时,衬底特性随温度的变化也将影响天线的性能.

| Abstract: | The performances of HTS microstrip antennas on anisotropic substrates are studied in this paper. The input impedance and radiation efficiency of HTS microstrip antennas on two typical HTS anisotropic substrates , GaNdAlO3 and SrLaAlO4 , are calculated using the modified spectral domain moment method in anisotropic materials. The results show that the anisotropic property of high-temperature superconductor substrates have an influence on the performances of HTS microstrip antennas, which varies with substrates, while the variation of the properties of HTS substrates with the temperature also affects the performances of antennas. |
