The full wave analysis of fractal antennas

The full wave method (FDTD) was used to analyse some fractal antennas. The computational results are in good agreement with the experiments for the Hilbert curve fractal antenna. The results show that fractal geometries can be implemented to miniaturize the antenna size compared to the normal antenna. Also the self-similar nature in the Sierpinski fractal geometry can be utilized for operating a fractal antenna at various frequencies. Furthermore, the far field patterns of the fractal antennas remain almost the same at their resonant frequencies.
