We have developed a superconducting filter for deep space exploration new antenna. An r-Al₂O₃ substrate has strong mechanical strength, high chemical stability and merit of low cost. However, there is the problem that it is difficult to agree well with the simulated and measured result. In this study, we proposed the design method which consider the dielectric anisotropy of the substrate. We accurately designed the superconducting filter which satisfied the design specification by using proposed method. Therefore, the measured results agree well with the simulated ones. Finally, our filter adopted for the receiving system of the JAXA Ground Station for Deep Space Exploration and Telecommunication (GREAT).
