Metamaterial based CPW band stop filter for WLAN application

Abstract

The proposed work presents a design of band stop filter with two pair of split ring resonators (SRR) placed symmetrically on the back side of a coplanar wave guide (CPW). Here novel configuration of SRR is inculcated to achieve band stop filter performance. This filter can suitably be used to restrict possible interference with existing WLAN band of frequency (5.24 GHz). The two pair of SRR which are placed just opposite side of CPW feed, serve the purpose of narrow band stop filter with an attenuation of nearly -25dB.
