Utilization of Electromagnetic Band Gap Cells for performance improvement of Co-Planar Waveguide Ultra Wide Band Filters

K. Muhammed Ibrahim, H. Umma Habiba


This paper presents the characteristic design of compact coplanar waveguide (CPW) band pass filter cascaded with electromagnetic band gap (EBG) resonator. The electromagnetic band gap resonator used in this design reduces the size and suppresses the harmonic response of the filter. An accurate bandwidth is achieved by alteration incidences of the announcement zeros at the pass ensemble edge. The designed filter exhibits a good upper stop band with rejection greater than 25dB below 20GHz.  Electromagnetic Band-Gap cells in combination with CPW structures are presented with good performance metrics.
