Frequency-adjustable coplanar waveguide series capacitance resonator

Abstract

The invention relates to a frequency-adjustable coplanar waveguide series capacitance resonator. The resonator comprises a first-layer dielectric material A, a second-layer dielectric material B and athird-layer dielectric material C, wherein a first metal layer A1, a second metal layer A2, a third metal layer A3, a fourth metal layer A4 and a fifth metal layer A5 are arranged on the first-layerdielectric material A, the second-layer dielectric material B is a dielectric material with an adjustable dielectric constant, a grounding plate metal layer C1 is printed on the third-layer dielectricmaterial C, an input end of the resonator is arranged at a left side of the first-layer dielectric material A, and an output end of the resonator is arranged at a right side of the first-layer dielectric material A. By changing the dielectric constant of the dielectric material B, the boundary condition between the first-layer dielectric material A and the second-layer dielectric material is changed, so that the resonant frequency point of the resonator is changed, and the frequency-adjustable coplanar waveguide series capacitance resonator is achieved.
