Study of Ultra Wide Stopband Filter (16.1GHz) Using DGS

and
  • In this paper a study of ultra wide stop band filter using DGS is presented. The LPF is comprised of Stepped Impedance Filter (SIF) with studies carried with different structures like (a) back to back C shaped DGS and (b) face to face C shaped DGS. This proposed design gives a wide stopband LPF. The substrate material is RT/Duroid5880 with dielectric constant 2.2 with the thickness of 0.502mm. The proposed LPF provides wide stopband from 2GHz to 18.1GHz the insertion loss is maintained at above -3dB and return loss is greater than 25dB for face to face C shaped DGS. The proposed design is simulated in Ansoft HFSS software and tested using VNA.

Abstract

In this paper a study of ultra wide stop band filter using DGS is presented. The LPF is comprised of Stepped Impedance Filter (SIF) with studies carried with different structures like (a) back to back C shaped DGS and (b) face to face C shaped DGS. This proposed design gives a wide stopband LPF. The substrate material is RT/Duroid5880 with dielectric constant 2.2 with the thickness of 0.502mm. The proposed LPF provides wide stopband from 2GHz to 18.1GHz the insertion loss is maintained in above -3dB and return loss is greater than 25dB for face to face C shaped DGS. The proposed design is simulated in Ansoft HFSS software and tested using VNA.
