Wideband Fractal Antenna For Ku Band Applications

Abstract

A Wideband rectangulsr patch antenna has been designed for the Ku band applications with an operating frequency range of 11.5GHz to 15.8GHz covering 4.3GHz of bandwidth. Patch has been etched with slots in a periodic manner which led for the generation of wideband bandwidth. Flame Retardant Glass epoxy is taken as substrate material which is having a thickness of 1.6mm and a 50Ω stripline has been used to excite the antenna. Fractal technique has been implemented to attain the wide bandwidth of operation. The overall dimension of the antenna is 60mm×60mm×1.6mm. The Proposed antenna is having wide bandwidth covering the ku band frequency range from 11.5GHz to 15.8GHz covering 4.3GHz of bandwidth with a return loss value less than -10dB for entire bandwidth. Commercially available 3D simulator Ansys HFSS software has been used to design the proposed antenna.
