Modeling of fractal antennas

Results on the numerical analysis of the Sierpinski and Koch fractal antennas are presented. It is shown that self-similarity of fractal structures affects electromagnetic properties of antenna structures created on the basis of these fractals. It is demonstrated that the Sierpinski and Koch fractal antennas are multiband structures; therefore, these antennas can be used for the development of radar and telecommunications systems. A technique is proposed for generation of an irregular determinate fractal structure that can be used for the development of a frequency-independent fractal antenna.
