Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>In this article, a compact ultra‐wideband (UWB) slot antenna with band‐notched performance is presented. To increase the impedance bandwidth of an ordinary slot antenna, we use a pair of S‐shaped slots in the ground plane that with this structure a new resonance at the higher frequencies can be achieved, and a wide usable fractional bandwidth of more than 130% is provided. Additionally, by cutting a rectangular slot with a rotated E‐shaped strip protruded inside the slot in the square radiating stub, a frequency‐notched band performance has been obtained. The designed antenna has a small size of 20 × 20 mm² while showing the radiation performance in the frequency band of 3.13 to over 14.3 GHz with a band rejection performance in the frequency band of 5–6 GHz. Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior within the UWB‐frequency range. © 2013 Wiley Periodicals, Inc.
