In this article, a novel printed monopole antenna is presented for simultaneously satisfying DCS, wireless local area network (WLAN), and worldwide interoperability for microwave access (WiMAX) applications.The operating frequencies of the proposed antenna are 1.8 GHz, which covers DCS operations, 2.4/5.2/5.8 GHz for WLAN system and 2.5/3.5/5.5 GHz for WiMAX system. The desired resonant frequencies are obtained by adjusting the length of folded Γ‐shaped arms. Also by cutting an H‐shaped slot in the bottom 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.
