In this article, a planar ultra‐wideband (UWB) antenna with dual rectangular notchband characteristics (ie, 5.94‐7.50 GHz and 8.02‐10.46 GHz) is presented. The two‐notch bands are chosen based on various wireless applications operating in C‐band and X‐band. The size of the antenna is very compact (25 × 25 × 1.6 mm3) and is designed on a low‐cost FR4 substrate. Co‐planar waveguide (CPW) feed and beveling techniques are utilized for achieving the UWB operation. In order to yield the first rectangular notch, a U‐slot and a pair of split‐ring resonators are embedded into the radiating patch and the backside of the design, respectively. The coupling between these two structures is adjusted so as to achieve a rectangular band‐notch operation. The second rectangular notch has been achieved by introducing the two mushroom type electromagnetic band‐gap structures on the opposite side of the CPW feed. The parametric analysis for controlling band notches, time‐domain analysis, and filter synthesis is also presented. Finally, simulated as well as measured results of S11, gain, radiation pattern, group delay, and total efficiency are demonstrated to show the suitability of this design for UWB systems.
