An ultra wideband (UWB) coplanar waveguide (CPW) fed rectangular monopole antenna, which is of band notched characteristic for Wireless Local Area Network (WLAN), Worldwide inter-operability for Microwave Access (WiMAX) and the C-band satellite communications, is proposed, fabricated and measured. In order to obtain the desired dual band rejections, a piece of pentagonal slotline and a pair of inverted L-shaped stubs are loaded on the CPW fed rectangular monopole antenna of enhanced impedance bandwidth. The antenna is printed on the FR4 substrate of 40 mm (width) × 41 mm (length) × 0.5 mm (thickness), and is optimized by ANSOFT HFSS. A prototype is fabricated according to the optimized parameters values, and the antenna characteristics are measured. The results show that the antenna is of UWB characteristic and exhibits band rejection of 3.2-4.25 GHz and 5.1-6.15 GHz, which covers WLAN, WiMAX, and C-band satellite communications.
