Abstract:
1. A coplanar waveguide resonator, comprising: a dielectric substrate; a center conductor formed on said dielectric substrate, and having a center line conductor; and a ground conductor disposed on said dielectric substrate with a gap section interposed between respective peripheral edges of the ground conductor and respective sides of said center line conductor; wherein a short-circuited line conductor is connected at both ends thereof perpendicularly to the peripheral edges of the ground conductor; said center line conductor at one end thereof is connected perpendicularly to a center of the short-circuited line conductor, and at the other end thereof is open-circuited, so that the center line conductor and the short-circuited line conductor constitute the center conductor in a T-shape; and the coplanar waveguide resonator further comprises, two base stubs, each base stub being formed as an extension of the ground conductor and having a first collateral line conductor, which is disposed in parallel to the center line conductor with a uniform distance from said center line conductor and is open-circuited at one end face; and a connecting line conductor, which is connected at one end as a root part of the base stub perpendicularly to the corresponding peripheral edge of the ground conductor and at the other end with the other end of said first collateral line conductor together, so that said first collateral line conductor and said connecting line conductor constitute the base stub in an L-shape.
