A printed quadruple band-notched ultra-wideband (UWB) antenna characteristic is presented. The designed UWB has a size of 32 mm × 30 1.6 and covers an impedance bandwidth off 2.9–14.5 GHz for the entire frequency band. band maintains voltage standing wave ratio (VSWR) <2, except at WiMAX (3.1–3.6 GHz), WLAN (4.92–6.12 downlink X-band satellite communication systems (7.5–8.4 (10.2–11 GHz). By...

This paper presents a novel ultra-wideband (UWB) antenna that rejects narrow and broad bands and is suitable for wireless communications. The base of the proposed antenna has a circular patch that can cover the UWB frequency range (3.1~10.6 GHz). The interference issues caused by co-existence within the UWB operation frequency are overcome by a design that uses a parallel-coupled asymmetric dua...
