  "abstract": "<p>In this thesis, Ultra Wide Band (UWB) antenna design with a large bandwidth and small<br>\nsize for Wi-Fi, WiMAX and 5G Networks is presented. The proposed antenna operates<br>\nat four different frequency bands from 2 GHz to 22 GHz for different applications with a<br>\nfractional bandwidth (FBW) of greater than 150%. The antenna is very compact with a<br>\nsize 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<br>\nis coplanar wave guide and a transmission line model of analysis has been implemented,<br>\nand simulated using CST software tools. The radiator patch of the antenna has an elliptical<br>\nstructure with a circular slot on the patch. In addition to this, a bending ground structure<br>\nwith two small rectangular slots is designed to achieve the desirable UWB properties. The<br>\nradiation pattern of the antenna is nearly omnidirectional that radiates in all directions in<br>\na given plane with a constant gain at the specified frequency range. The performance of<br>\nthe antenna is shown using various parameters, such as voltage standing wave ratio, gain,<br>\nreturn loss, directivity and radiation patterns.<br>\niv</p>",
