    <description descriptionType="Abstract">&lt;p&gt;In this thesis, Ultra Wide Band (UWB) antenna design with a large bandwidth and small&lt;br&gt;
size for Wi-Fi, WiMAX and 5G Networks is presented. The proposed antenna operates&lt;br&gt;
at four different frequency bands from 2 GHz to 22 GHz for different applications with a&lt;br&gt;
fractional bandwidth (FBW) of greater than 150%. The antenna is very compact with a&lt;br&gt;
size of 18:25x15:2mm2 and designed using FR-4 dielectric substrate material having permittivity of 4.4 and height of 1.6mm. The proposed feeding scheme in this antenna design&lt;br&gt;
is coplanar wave guide and a transmission line model of analysis has been implemented,&lt;br&gt;
and simulated using CST software tools. The radiator patch of the antenna has an elliptical&lt;br&gt;
structure with a circular slot on the patch. In addition to this, a bending ground structure&lt;br&gt;
with two small rectangular slots is designed to achieve the desirable UWB properties. The&lt;br&gt;
radiation pattern of the antenna is nearly omnidirectional that radiates in all directions in&lt;br&gt;
a given plane with a constant gain at the specified frequency range. The performance of&lt;br&gt;
the antenna is shown using various parameters, such as voltage standing wave ratio, gain,&lt;br&gt;
return loss, directivity and radiation patterns.&lt;br&gt;
