Abstract
A low-proflle microstrip planar monopole antenna with triple-band operation for WiMAX and WLAN applications is proposed in this paper. The antenna has a simple structure which consists of a rectangular ring patch, two inverted L-shaped strips extending from the rectangular ring patch, and a microstrip feed line. By adding two L-shaped strips on the rectangular ring patch, three resonant modes can be excited independently. The antenna has a simple structure and a compact size of 21 £ 33 £ 1:6mm 3 . The measured i10dB impedance bandwidth of the proposed antenna covers 2.39{ 2.51GHz, 3.26{4.15GHz, and 5.0{6.43GHz, which can fully cover the 2.4/5.2/5.8GHz WLAN bands and 3.5/5.5GHz WiMAX bands. A prototype is fabricated, and then measured. The experimental and simulation results show good impedance bandwidth, radiation pattern and stable gain across the operating bands.
