Design of a UWB Antenna Utilising Fractal Geometry and EBG Structures for Wireless Applications

The analysis of fractal antenna designed for ultra wide band (UWB)characteristics are presented in this work. To enhance the antenna's radiating properties, fractal technology is used. The suggested fractal antenna has a 9 GHz impedance bandwidth with a range of 3 GHz to 12 GHz, a maximum gain of 3 dB, and an efficiency of 89%. Electromagnetic bandgap structures are integrated into the antenna and shorted at the ground in order to improve band rejection characteristics in the WLAN band and create band notched characteristics in the WLAN and satellite downlink band. In order to analyse the antenna, CST Microwave Studio is used.
