Abstract :
Several types of coplanar waveguide (CPW) resonator are analyzed by use of the field decay method based on the FDTD algorithm. Quality (Q) factors of a CPW resonator, including radiation Q, conductor Q, dielectric Q and unloaded Q, are investigated thoroughly. Some CPW resonators are fabricated and measured in order to validate the analysis method
