A novel CPW-FED circular square-corner fractal antenna with varying notch-band for UWB applications
The design of this paper represents the novel cpw-fed circular square corner fractal antenna with varying notch-band frequency characteristics. The position and width of the notch-band can be adjusted in the entire operating band. A prototype of the antenna has been designed on FR4-Epoxy substrate dielectric constant 4.4 and thickness h=1.53 mm with a N-shape slot in coplanar waveguide feed of length L = 7.4 mm and slot width W = 2.8 mm. The experimental result of this antenna exhibits ultra wide band characteristics from frequency 3.1 GHz to 15.0 GHz. The notch in operating band helps to reduce the interference with the frequency bands of Wireless Local Area Network (WLAN). The simulated and experimental return losses are found in good agreement. The experimental radiation of this antenna in azimuth plane is nearly omni-directional. This proposed cpw-fed circular square corner fractal antenna with varying notch-band frequency characteristics can thus be used for Ultra wide band (UWB) system, microwave imaging, precision position system, and radar tracking system.
