Abstract
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×24 mm×1.6 mm is excited by a 50Ω microstrip feed line. The band-notch functions are realized by loading two approximate half-wavelength U-shaped slots which change the current distribution on the Y-shaped patch. The obtained results show that the designed antenna has an impedance bandwidth of 2.95 GHz-12 GHz for S11 ≤ -10 dB, except two frequency stop-bands of 3.32 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.
