Design of a Dual Stop-Band Filter Based on Coplanar Waveguide
This letter presents a dual stop-band filer based on coplanar waveguide (CPW), which consists of two spiral-shaped defected ground structure (DGS). The model of the equivalent circuit, discussing the influence of the spiral shape size, and simulated performances are presented. Finally, a dual stop-band filter is presented and verified by simulations, which is operated from 11.5 to 14 GHz and 23 to 28 GHz.
