Abstract

In this paper a novel Ultra Wide Band textile antenna is designed which operates from 2.6-14 GHz, covering entire Ultra Wide Band frequency range of 3.1-10.6 GHz, as approved by FCC. The proposed antenna consists of a octagonal patch and a partial ground plane with a square notch. The substrate of the designed antenna is made of Dacron fabric (ε <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> =3) while patch and ground is made of copper tape. The dimension of the substrate is 43×34 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Simulated results of different antenna parameters such as return loss (S11), gain and radiation patterns are presented. This antenna performance are also analysed at four different bending angles. The characteristics, low profile and compact size of the proposed antenna depicts as a potential candidate for UWB applications. The antenna design details and simulated results are presented by CST microwave studio.
