Patent number: 7411475Abstract: A superconductor filter comprises a plurality of resonance elements arranged between input-output lines formed on a substrate. Metal conductor sections serving to inhibit the spatial coupling between the adjacent resonance elements are arranged between prescribed resonance elements, and a prescribed resonance element is coupled with another resonance element by a coupling transmission line. It follows that each resonance element is coupled with another resonance element by the direct coupling via the coupling transmission line or by the spatial coupling via the space.Type: GrantFiled: March 13, 2007Date of Patent: August 12, 2008Assignee: Kabushiki Kaisha ToshibaInventors: Hiroyuki Fuke, Yoshiaki Terashima, Fumihiko Aiga, Mutsuki Yamazaki, Hiroyuki Kayano, Tatsunori Hashimoto

Patent number: 7305261Abstract: A band pass filter which is configured by a microstrip line, or a strip line is provided. The band pass filter has a first half wavelength resonator which resonates at a center frequency of a pass band, a second half wavelength resonator which resonates at the center frequency of the pass band, and a transmission line through which the first half wavelength resonator is wire-coupled to the second half wavelength resonator.
