Abstract

AbstractA novel small CPW feed UWB antenna with five notch bands is projected to suppress the potential interferences in ultra-wideband systems. This projected antenna has a small dimension of 30x32x1.6 mm3 and an operating bandwidth (VSWR<2) from 2.8 to 11.6 GHz. By introducing five U-shaped slots, five notches are achieved in WiMAX (3.1–4 GHz), WLAN (5–5.4 GHz and 5.7–5.9 GHz), X-band downlink (7.2–7.75 GHz), and ITU service band (8–8.4 GHz). The antenna is fabricated and simulated. Measured results show a good harmony with simulated results. In addition, the projected antenna has omnidirectional radiation patterns except for notch bands; make it suitable for UWB applications.Keywords: UWB, notch band, WiMAX, WLAN, X-band, ITU
