Size miniaturized fractal antenna for 2.5GHz application
In this paper fractal technique is analysed for antenna miniaturization. The space filling property of fractals is used for size reduction of patch antenna. By the application of fractal technique, the effective electrical length of the antenna is increased for the same resonant frequency. However, the fractal antenna has the same radiation pattern and input impedance as a conventional antenna. In our work, we use the Koch fractal for size reduction of circular patch antenna. 45% reduction in operating frequency and 21% reduction in size has been achieved in proposed design. Analysis of antenna is done in CST Microwave Studio.
