A New Fractal Based Printed Slot Antenna for Dual Band Wireless Communication Applications

Abstract

Different fractal based structures have been widely used in numerous antenna designs for various applications. In this paper, a printed slot antenna has been introduced as a candidate for use in the dual band wireless communication applications. The antenna slot structure is in the form of a Sierpinski gasket of the first iteration. The antenna has been fed with 50Ohm microstrip transmission line, and the slot structure is to be etched on the reverse side of the substrate. Performance evaluation of the proposed antenna design has been carried out using a method of moments based EM simulator, IE3D. Simulation results show that the<br>resulting antenna exhibits an interesting dual frequency resonant behavior making it suitable for dual band communication systems including the dual band WLAN applications. Parametric study has been carried out to explore the effects of antenna parameters on its performance.
