Circular patch with star triangular fractal antenna for SWB applications

A star triangular fractal antenna with semi elliptical ground plane is presented for SWB application. A fractal is a recursively generated object having a fractional dimension. Many objects, including antennas can be designed using the recursive nature of a fractal. The fractal antennas that have the multiband operation due to the self-similar property in fractal geometry, which plays a key role to create a star triangular fractal antenna. The other important property is space filling property which determines the reduction in the size of the antenna. The design process of the proposed structure for improving of the impedance bandwidth and improve the efficiency of the antenna. The antenna is designed up to 5^th iteration. The antenna operates over a frequency range between 1-30 GHz. We have studied the effect of iteration and making it for different wide band application. Iteration is done by using IFS. IFS used to generate the fractal structure.
