Design of 4th Order Microstrip High Pass Filter Using Wrist Watch Shaped Defected Ground Structure at 2.5 GHz

Download Paper


The performance of a high pass filter (HPF) with and without Defected ground structure has been analyzed. The Defected Ground Structure is in “wrist watch” Shape. Parameters of the proposed configuration were calculated at the centre frequency of 2.5 GHz 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 are concentrated by using modified ground structure. Also the cutoff point of the high pass filter is shifted to a higher frequency and an enhancement in selectivity. The filter can be useful in various RF circuits where fewer fluctuations are required in pass band.
