A compact printed quadruple band-notched UWB antenna

Abstract

A novel compact coplanar waveguide- (CPW-) fed ultrawideband (UWB) printed planar volcano-smoke antenna (PVSA) with four band-notches for various wireless applications is proposed and demonstrated. The low-profile antenna consists of a C-shaped parasitic strip to generate a notched band at 8.018.55 GHz for the ITU band, two C-shaped slots, and an inverted U-shaped slot etched in the radiator patch to create three notched bands at 5.155.35 GHz, 5.755.85 GHz, and 7.257.75 GHz for filtering the WLAN and X-band satellite signals. Simulated and measured results both confirm that the proposed antenna has a broad bandwidth of 3.112 GHz with VSWR < 2 and good omnidirectional radiation patterns with four notched-bands. © 2013 Xiaoyin Li et al.
