A CPW Feed Compact UWB Antenna with Five Band Notches

Ajeet Pratap Singh, R. Khanna, Hardeep Singh

Abstract


A novel small CPW feed UWB antenna with five notch bands is projected to suppress the potential interferences in ultra-wide band systems. This projected antenna have a small dimensions 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 notch bands; make it suitable for UWB applications.
