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) 1997Dr.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) 1998Prof.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.

通过山形大学和伍珀塔尔大学的联合研究，我们获得了一些关于高温超导滤波器和天线的新成果，结果如下：(1) 1997年博士。Kusunoki参观了伍珀塔尔大学chaloupka教授的实验室，研究了超导滤波器的设计。本课题组研究了YBCO薄膜的形成过程，并对其超导性能进行了测试。我们还设计了超导天线和滤波器。Chaloupka的团队研究了超导过滤器。(2) 1998年教授。Chaloupka在我们的实验室呆了大约三个星期，和我们一起开发超导过滤器。他在我实验室期间，在山形大学举办了高温超导过滤器研讨会。设计了具有窄带宽、尖裙边特性和小插入损耗的交叉耦合超导滤波器。山形大学（大岛的实验室）和伍珀塔尔大学（Chaloupka的实验室）的联合工作将在1999年继续进行。
