A printed monopole antenna for UWB applications with dual band notch property is proposed in this letter. The UWB monopole consists of modified circular patch with an elliptical slot to reject WiMAX frequencies (3.3–3.8 GHz). The modified ground plane is introduced to attain the wide impedance UWB bandwidth with G‐shaped slot below the feed line to reject 5.15–5.85 GHz WLAN frequencies. The length of embedded slot not only depends on notch frequency and substrate dielectric constant but also depends on substrate thickness and slot width. In this letter, we have presented a technique to calculate accurately the slot length of the embedded slot. The simulated and measured result shows that the designed antenna is expected to be good candidate for UWB applications. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:99–104, 2015
