Compact printed high rejection triple band-notch UWB antenna with multiple wireless applications

Abstract

In this paper, small printed urn-shape triple notch ultra-wideband (UWB) monopole antenna with diverse wireless applications is presented. Notch bands include WiMAX (IEEE802.16 3.30–3.80GHz), WLAN IEEE802.11a/h/j/n (5.15–5.35GHz, 5.25–5.35GHz, 5.47–5.725GHz, 5.725–5.825GHz), and X-band downlink satellite system (7.25–7.75GHz) and other multiple wireless services as close range radar (8–12GHz) in X-band & satellite communication (12–18GHz) in Ku-band. By including T-shape stub and etching two C-shaped slots on the radiating patch, triple band-notch function is obtained with measured high band rejection (VSWR=16.54 at 3.60GHz, VSWR=22.35 at 5.64GHz and VSWR=6.38 at 7.64GHz) and covers a wide useable fractional bandwidth of 154.56% (2.49–19.41GHz). In short the antenna offers triple band-notch UWB systems as a compact multifunctional antenna to reduce the number of antennas installed in wireless devices for accessing multiple wireless networks with wide radiation pattern.
