摘要：

This article presents the design of diamond shape fractal antenna with coplanar waveguide feed for ultra-wide bandwidth. This new fractal antenna has been designed on substrate epsilon(r) = 4.3 and thickness h = 1.53 mm. The antenna has been constructed incorporating fractal geometry in a circular disc of 30 mm diameter. The experimental result of this proposed antenna exhibits the excellent ultra-wide bandwidth from 2.05 GHz to 6.245 GHz. The detail parametric studies have been carried out using electromagnetic simulator HFSS10. The experimental results are in close agreement with the simulated results. The experimental radiation patterns are nearly omni-directional in H-plane and dumble shape in the E-plane throughout the frequency band of interest. The measured group delay of this antenna is stable throughout the band. Such type of antenna is useful for ultra-wideband communication system, microwave imaging and precision positioning system.
