Abstract

In this proposed paper, the performance of band stop filter with modified ground structure is examined; the modified ground structure includes four rectangular and a hexagonal etched shapes in ground plane. Parameters of the proposed design were calculated at the cut off frequencies of f1=1.16 GHz, f2=1.89 GHz and also proposed designs having substrate height of 1.6 mm, loss tangent of 0.02 and dielectric constant of 4.4. Results are calculated using computer simulation technology software (CST). The undesired side bands and fluctuations of response are reduced by using modified ground structure.
