ABSTRACT:
A coplanar waveguide resonator (100a) has a center conductor (101) formed on a dielectric substrate (105) that has a line conductor (a center line conductor) (101b) extending in the input/output direction, a ground conductor (103) that is disposed on the dielectric substrate (105) across a gap section from the center conductor (101), and a line conductor (a base stub) (104) formed as an extension line from the ground conductor (103), and a part of the base stub (104) constitutes a line conductor (a first collateral line conductor) (104a) disposed in parallel with the center line conductor (101b).
