A compact multiband antenna for WLAN and WiMAX applications

A compact printed monopole antenna applied to wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications is proposed. By combining a C-shaped strip and two L-shaped strips, fed by a 50-Ω microstrip transmission line, multiple impedance bandwidths covering WLAN/2.4/5.2/5.8 and WiMAX/3.5 are obtained. Further, the proposed antenna occupies a small size of 35 × 20 mm2, and has good radiation characteristic and peak gains to be 2.77, 2.92, and 3.04 dBi at 2.45, 3.5, and 5.5 GHz, respectively. © 2011 Wiley Periodicals, Inc.
