Abstract

In this article, a novel printed monopole antenna for ultra wideband applications with variable frequency band‐notch characteristic is presented.The proposed antenna consists of an E‐shaped radiating patch with two L‐shaped arms and a T‐shaped arm which provides a wide usable fractional bandwidth of more than 130% (2.9–14 GHz). By inserting two modified L‐shaped arms with variable dimensions on the E‐shaped radiating patch frequency band‐stop performance is generated and also by inserting T‐shaped arm this performance is improved. We can control band‐stop performance characteristics such as band‐notch frequency and its bandwidth. The designed antenna has a small size of 10 × 17 mm^2^ while showing the band rejection performance in the frequency band of 5.01–5.98 GHz. © 2011 Wiley Periodicals, Inc.
