In this article, a novel design of band‐notched monopole antenna with U‐shaped slot capable to work for both WLAN (2.4 – 2.5 GHz) and UWB (3.1‐10.6 GHz) applications is proposed. This antenna comprises the multilateral structure of the circular radiating patch with U‐shaped slot fed by a 50Ω microstripline feed and on bottom of the antenna a partial ground plane is used. A U‐shaped slot is etched on the circular radiating patch. With this design the antenna gives the WiMAX (3.2‐4.2 GHz) band‐notched characteristics. The parametric study of the proposed antenna is investigated using the Ansoft HFSS software and the results are compared with experimental results and they are good in agreement with each other. The antenna can operate in the range of 2.36 to more than 12 GHz with notched band of 3.3‐4.20 GHz for 3.5 GHz WiMAX. Also, this antenna exhibits a good omni‐directional radiation patterns and stable peak gain over the desired frequency bands which will satisfy the UWB communication system. © 2015 Wiley Periodicals, Inc.
