Title:Optimization of Dual-Band BPF using Defected Ground Structure
Author Name:Anjali Sachan, Arvind Kumar Pandey and R.K. Chauhan
Synopsis:
In this paper, a new Defected Ground Structure (DGS) is proposed with an aim to reduce the size of already existing filter and increase the fractional bandwidth of the band-pass filters. The proposed DGS is applied to the previously designed Dual-Band Pass Filter (BPF), which was operating at 2.45 GHz and 5.2 GHz. On using this defected ground structure, the operating frequency of the first pass band reduces from 2.45 GHz to 2.197 GHz, whereas operating frequency of second pass band reduces from 5.2 GHz to 4.8 Ghz. The increase in fractional bandwidth was also observed at first pass-band.
The size of the Dual-Band BPF with DGS is 0.11 λ × 0.21 λ , and size of Dual-Band BPF without DGS is 0.11λ × 0.23λ . The g g g g size of the Dual-Band BPF is therefore reduced to 8.69% after using the proposed DGS.
