A simple printed monopole antenna with tunable slots is proposed for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications.The antenna structure consists of a semicircular ground and a rectangular patch with four round corners. By etching a couple of slots in the patch, the notched band from 3.7 to 4.8 GHz can be obtained. Furthermore, by adjusting the length and position of the slot, we make the notched band tunable both the center frequency and bandwidth. The proposed antenna is successfully designed and measured. The measured 10 dB bandwidth for return loss covers both the 2.4/5.2/5.8 GHz WLAN bands and 2.5/3.5/5.5 GHz WiMAX bands. © 2010 Wiley Periodicals, Inc.
