Abstract

A novel wideband wireless local area network/worldwide interoperability for microwave access (WLAN/WiMAX) hybrid antenna comprised of an asymmetric rectangular patch and additional strips is presented, including both simulation and measurement results. This proposed hybrid antenna exhibits wideband performance with sufficient bandwidth to meet the requirements of WLAN in the 2.4/5.2/5.8 GHz bands and WiMAX in the 2.5/3.5/5.5 GHz bands. Measurements show that the 10 dB return loss bandwidth (VSWR < 2) reaches as much as 5.59 GHz (= 7.92 GHz − 2.33 GHz). Moreover, the antenna gains at 2.45 GHz, 3.55 GHz, and 5.85 GHz are measured to be 4.596 dBi, 3.126 dBi, and 5.42 dBi, respectively. © 2009 Wiley Periodicals, Inc.
