A compact microstrip fed monopole antenna with dual band‐notch function is proposed for ultrawideband applications. The antenna consists of a rectangular radiating patch one side and solid ground up to the half length of the antenna on the other side. The band notch functions are achieved by etching two back‐to‐back C‐shaped slot in the rectangular metal radiating patch. Combination of each notch element on the UWB antenna is aimed for providing dual band rejection function at WLAN 2 (5.15–5.825 GHz) and ITU 8 GHz (8.025–8.4 GHz). The measured results reveal that the presented dual band‐notch monopole antenna offers a very wide bandwidth with two notched bands from 5.2 to 5.96 GHz and 7.84 to 8.4 GHz. The prototype with overall size of 26 × 32 × 762 mm 3 achieves good impedance matching, voltage standing wave ratio, constant gain, and stable radiation patterns, over an entire operating bandwidth of 2.8–12.16 GHz. © 2013 Wiley Periodicals, Inc.
