Fractal Antenna Design for UWB Applications

Abstract

Development and advancement in the field of wireless communication has led to the demand of high data rate and compact antenna design with broadband characteristics. Frequency from 3.1 GHz to 10 GHz has been allowed by FCC for commercial use from 2002. This frequency range is usually used for short range communication. This calls upon the problem of interference with other system working on same frequency band. Fractals means discontinuous or irregular in shape, its geometry cannot be described by normal geometry. The term was coined by Manderbolt. It contains multiple copies of it in different dimensions. Fractals have been used here to design an antenna for the same. The reason for fractals is smaller size, it produces discontinuity i.e. corners and bends which in turn produces higher efficiency and provide multiband characteristics as well.
