| Research Abstract |
We could obtain some new results of HTS filters and antennas by the joint study between Yamagata University and Wuppertal University, The results are as follows.
(1) 1997
Dr.Kusunoki visited the laboratory of Prof.Chaloupka in Wuppertal University and researched about design of superconducting filters. Our group had investigated the formation process of YBCO thin films and measured its superconducting properties. We also designed superconducting antenna and filters.
Prof.Chaloupka's group investigated superconducting filters.
(2) 1998
Prof.Chaloupka stayed our laboratory for about three weeks and coworked with us to develop superconducting filters. During his stay in our laboratory the symposium of HTS filters was held in Yamagata University. We designed cross-coupled superconducting filters which had narrow bandwidth, sharp skirt properties and small insertion loss.
The joint work between Yamagata University (Ohshima's laboratory) and Wuppertal University (Chaloupka's laboratory) will be continued in 1999.
