PROBLEM TO BE SOLVED: To provide a resonator where connection adjustment of resonators with each other and miniaturization are easy and a conductor loss is reduced. SOLUTION: Line parts on a short circuit side of respective lines constituting two 1/4 wavelength resonators 1 and 2 are made to be common as a common line part 22, and the respective 1/4 wavelength resonators 1 and 2 are coupled with each other at the common line part 22. Since a part of the line is made to be common, miniaturization becomes easy. Moreover, the conductor loss due to coupling is reduced. By adjusting the length (x) of the common line part 22, the coupling adjustment is carried out easily. COPYRIGHT: (C)2007,JPO&INPIT
