Resonant and coupling characteristics of miniaturized microstrip spiral resonators are investigated first. Then a 4-pole Chebyshev bandpass filter with a very narrow passband (4.1 MHz) is designed and realized using microstrip spiral resonators. The filter is fabricated using HTS YBCO films deposited on a LaAlO_3 substrate. The measured frequency response of the filter agrees reasonably with the specifications, and shows that the filter owns excellent property of spurious resonance rejection over a wide frequency range., copyright(c)2005 IEICE 許諾番号:07RB0174  http://www.ieice.org/jpn/trans_online/index.html, text, application/pdf}, pages = {216--220}, title = {Design and Measurement of a Miniaturized HTS Filter Using Microstrip Spiral Resonators(Microwaves, Superconducting Electronic Devices and Their Applications)}, volume = {E88-C}, year = {2005}, yomi = {マ, テツオウ and サクライ, エリト and コバヤシ, ヨシオ} }
