Abstract

In this article, a novel printed dipole antenna using log‐periodic toothed structure is presented for simultaneously satisfying wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The operating frequencies of the proposed antenna are 2.4/5.2/5.8 GHz, which covers WLAN system and 2.5/3.5/5.5 GHz for WiMAX system. The desired resonant frequencies are obtained by adjusting the number of log‐periodic teeth. Also by cutting two slots in the both sides of microstrip feedline on the ground plane, much wider impedance bandwidth can be produced. Prototypes of the proposed antenna have been constructed and studied experimentally. The measured results show good agreement with the numerical prediction and good multiband operation. © 2011 Wiley Periodicals, Inc.
