| Abstract: | CPW and fractal structure used together in antenna design have unique advantages in broadening the bandwidth of the antenna. A novel copper-cash-shaped ultrawideband(UWB) fractal antenna was proposed. By using fractal slot， the CPW-fed antenna had a wide bandwidth. Surface current distribution， return loss， directional patterns and gain of the antenna were investigated. Three iterative fractal antenna was fabricated and measured. The measured results show that the bandwidth is 2.6~16 GHz， larger than 6:1， and found in good agreement with the simulated results. Thus this antenna can be widely used in compact structure and UWB antenna design. |
