摘要：
A novel Ultra-Wideband (UWB) monopole antenna is proposed that exhibits stop-band functionality at the WLAN frequency band. It consists of an annular ring shaped radiating patch that is excited with a 50 Omega feedline. The stop-band is generated by etching a parasitic ring on the reverse side of the antenna's substrate. The antenna's impedance bandwidth was enhanced by including a semi-circular notch in the trapezoidal shaped ground-plane in the vicinity of the parasitic ring. The measured results confirm the impedance bandwidth covers a frequency range between 2.42-11.4 GHz for VSWR <= 2, which corresponds to a fractional bandwidth of 130%. The UWB antenna is omni-directional in the xz-plane and approximately hi-directional in the yz-plane. The antenna is compact in size with overall dimensions of 30x30x1.6 mm(3).
