| Abstract(in English) | A high-temperature superconducting (HTS) compact bandpass filter (BPF) for deep space exploration receiving system is developed by using r-Al2O3 substrate. An r-Al2O3 substrate has strong mechanical strength, high chemical stability and low cost. However, there is the problem that it is difficult to agree well with the simulated results and measured ones, because of dielectric anisotropy, so that there is no practical superconducting filter with r-Al2O3 substrate. Therefore, we determined the optimum dielectric constant for simulation to reduce the effect of dielectric anisotropy of the substrate. We designed and analyzed a 7-pole HTS BPF. The filter was fabricated using YBa2Cu3Oy thin film on r-Al2O3 substrate. The measured result agrees well with the simulated one and satisfied the design specification accurately. Finally, our filter was adopted for the receiving system of the JAXA Ground Station for Deep Space Exploration and Telecommunication (GREAT). |
