Abstract
In this paper, the novel method is proposed to realize the parallel coupled line band pass filter using defected ground structure(DGS) inverter. This method provides simple solution which easily resolves the limit of line width happened due to high impedance on the occasion of designing filter composed of line inverter. On the basis of the proposed method and conventional method, the band pass filters haying 13.3% fractional bandwidth were designed and implemented. The measured data of two filters show usually good agreement with each other, but on the other hand the length of proposed filter become shorten about 15mm and the width of inverter line was expanded two times or more in comparison with conventional filter.
