A Compact CPW-fed Quadruple-band-notched Antenna with Concentric Annular-rings for UWB ApplicationsBy Un Chol Kim, Hyon Jin Kim, Jong Yol Choe, Chol Ryong Kim, Myong Su Hong, Kwang Il Ri
Abstract: In this paper, a compact coplanar waveguide (CPW)-fed quadruple-band-notched antenna with concentric annular-rings for ultra-wideband (UWB) applications is presented. The proposed antenna consists of four concentric annular-ring resonators, a circular shape radiating element and a CPW feed line. The quadruple band rejection is easily achieved by controlling the widths and radii of four concentric annular-ring resonators. Through the exception of four stop-bands at 3.29 to 3.7 GHz, 5.07 to 5.92 …
