Abstract :
In this paper, a compact coplanar waveguide (CPW) resonant cell is introduced, which can exhibit dual-bandgap characteristics by only single unit. The same pattern has been adopted in the microstrip line as reported previously and here is applied to CPW. Experimental results show good agreement with numerical results. By alternating the relative position between CPW defected ground structure (DGS) and split-ring resonator (SRR), the separation between the two resonant frequencies can be controlled easily.
