Abstract

The performance of a High Pass Filter (HPF) with and without Defected Ground Structure (DGS) was analyzed. The defected ground structure is circular etched shapes in ground plane. Comparison of the response of filter with and without DGS was done separately. Parameters of the proposed configuration were calculated at the centre frequency of 1.5 GHz and with dielectric constant of 4.4, loss tangent of 0.02 and substrate height of 1.6mm. Results were simulated using computer simulation technology software (CST). The undesired sidebands and fluctuations of response were reduced by using defected ground structure (DGS).

Keywords: High Pass Filter (HPF), Defected Ground Structure (DGS), Computer Simulation Technology Software (CST).
