In this letter, a novel ultra wideband monopole antenna with frequency band-stop performance is designed and manufactured. The proposed antenna consists of two E-shaped structures in the radiating patch with a rotated Eshaped slot in the ground plane. The rotated Eshaped slot increases the bandwidth that provides a wide usable fractional bandwidth of more than 110% (3.05-11.50 GHz). In order to create bandrejected function, we use an E-shaped structure in the radiating patch and also by inserting a rotated coupled E-shaped strip we can improve bandnotched performance and a frequency notch band of 5.07–5.92 GHz has been achieved. Good return loss and radiation pattern characteristics are obtained in the frequency band of interest. Simulated and measured results are presented to validate the usefulness of the proposed antenna structure for UWB applications.
