摘要：
A compact ultrawideband (UWB) monopole antenna with two U-shaped slots for WLAN and WiMAX dual band-notched functions is proposed and experimentally studied. The proposed antenna with the size of 28 mm x 24 mm x 1.6 mm is excited by a 50 Omega microstrip feed line. The band-notch functions are realized by loading two approximate half-wavelength U-shaped slots which change the current distribution on theY-shaped patch. The obtained results show that the designed antenna has an impedance bandwidth of 2.95 GHz-12 GHz for S-11 <= -10dB, except two frequency stop-bands of 332 GHz-3.98 GHz for WiMAX and 4.81 GHz-6.68 GHz for WLAN. The antenna has successfully fabricated and measured. The return loss, band-notched characteristic, radiation patterns and peak gains are presented.
