Design of Reconfigurable Defected Ground Structure Resonator for C, X and Ku Band Application

In this Article., the reconfigurable defecate ground structure (DGS) resonator design is presented by using the coplanar waveguide (CPW) technology. The DGS resonator can be used in various applications such as Radar communication., X band application and satellite communication to produce band stop and band pass response simultaneously. However., from two different pin diode configuration is obtained from RLC equivalent circuit. The frequency range obtained from these two configuration is 1 to 18 GHz. The reconfigurable DGS resonators design is implemented and investigated with a duroid dielectric substrate which is having dielectric constant of 2.2 and thickness 0.234 mm. The achieved configuration capable to handle three different frequency of 8.36 GHz., 11.26 GHz and 13.46 GHz respectively. The design and simulation is done with the help of HFSS software. The simulated result shows the better performance.
