Abstract
A novel printed antenna with dual widebands is proposed and studied for simultaneously satisfying wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. In this study, the configuration consists of a back-to-back F-shaped monopole antenna with a microstrip feedline for excitation and an elliptic conductor-backed plane for band broadening. This antenna has a satisfactory impedance bandwidth sufficiently cover the 2.4/5.2/5.8 GHz WLAN bands and 2.5/3.5/5.5 GHz WiMAX bands.
