The first type is developed by using small-sized microstrip spiral resonators, and the second type by coplanar waveguide quarter-wavelength resonators. The filters have greatly reduced size compared with most previous HTS filters. They are designed by employing an electromagnetic simulator in combination with appropriately chosen equivalent circuits. Their measured frequency responses agree well with theoretical predictions, and show low insertion losses in spite of their small sizes., text, application/pdf}, pages = {14--17}, title = {スパイラル共振器を用いた小形高温超電導マイクロ波フィルタの研究<論文>}, volume = {38}, year = {2005}, yomi = {カワグチ, タミオ and マ, テツオウ and コバヤシ, ヨシオ} }
