A Printed Tree Fractal Based Cross Slot Antenna for 2.45GHz

Fractal based structures have been widely used in numerous antenna designs for several applications. In this paper, a printed tree fractal based cross slot antenna operating at 2.45GHz frequency is presented. The slot is in the form of a modified fractal tree structure etched on the ground plane. The slot has been fed electromagnetically by using a microstrip transmission line etched on the back side of the substrate. The printed tree fractal based cross slot antenna resonates at 2.45GHz with bidirectional radiation pattern.
