Abstract :
In this paper, a printed diversity Cantor set fractal antenna for ultra wideband (UWB) applications is proposed. The antenna consists of two identical wide slot antennas and the radiation patches are designed by using Cantor set fractal technology. The proposed antenna operates over a wide band spanning from 4.5 GHz to 10.6 GHz. The diversity antenna has a high isolation over 20dB. The high isolation is obtained using multiple slots etched in its CPW ground plane. The return loss and the isolation of the antenna are investigated by means of HFSS. The diversity performance of the antenna is assessed by isolation and radiation patterns. The results show that the proposed antenna provides stable patterns diversity, which enables the designed antenna to combat multi-path in wireless channels used in UWB systems.
