High Pass Filter Analysis using DGS

Abstract

In this paper, performance of High Pass Filter (HPF) with and without Defected Ground Structure (DGS) has been analysed. The defected ground is in ‘wrist watch’ shape with two symmetrical circles on either side from centre. In this proposed paper, simulation has been done on both the designs separately and the results of both the designs have been compared. The cut- off frequency of filter is 1.5 GHz. The filter can be useful in various RF circuits where less fluctuations are required in pass band.
