摘要

A novel planar ultrawideband monopole antenna with dual notched bands isrnpresented. The antenna mainly consists of a radiation patch and a modified ground plane.rnTo realize dual band-notched characteristics, a U-shaped stub embedded in the rectangularrnslot of the radiation patch and a novel coupled open-/shorted-circuit stub resonator arernused on the backside of the substrate. The bandwidth of the dual notched bands can be controllablernby adjusting some key parameters. The simulated and measured results indicaternthat the proposed antenna offers a very wide bandwidth from 2.6 to 18 GHz with VoltagernStanding Wave Ratio (VSWR) < 2, except the dual notched bands of 3.3–3.7 GHz (WorldrnInteroperability for Microwave Access [WiMAX]) and 5.15–5.825 GHz (Wireless LocalrnArea Network [WLAN]). Furthermore, good group delay and stable gains can be achievedrnover the operating frequencies.
