Abstract:
A planar triple-band monopole antenna with a U-shaped stripline and a L slot is presented. The antenna is very compact with a size of 20×30×1.5 mm3 and fed by a 50 Ω microstrip line with a defected ground. The measured -10dB impedance bandwidth of the proposed antenna covers 2.33 GHz-2.51 GHz, 3.25 GHz-3.82 GHz, and 4.83 GHz-8.4 GHz, respectively, which meets the specifications of WLAN 2.4/5.2/5.8GHz and WiMAX 3.5/5.5 GHz. The radiation characteristics shows a monopole-like pattern, and the measured results are in agreements with the simulated ones.
