The base of fractal antenna theory and applications: Utilizing in electronic devices

Computer simulation is employed to simulate the electrodynamic parameters of new fractal antennas and frequency-selective surfaces based on such antennas at the frequency range up to 20 GHz. The analysis of the original fractal antennas is supplemented with the study of the fractal frequency-selective 3D media or fractal sandwiches (i.e., radioelectronic fractal micro/nanostructures that contain not less than two layers). The efficiency of the fractal antennas and the fractal frequency-selective 3D media is demonstrated. The methods to create new passive electron components and elements for modern broadband and multifrequency radio systems based on such media are proposed. These samples have been obtained within the framework of the new fundamental scientific direction “Fractal Radio Physics and Fractal Radio Electronics: Designing of the Fractal Radio Systems”, which has been proposed and developed in Kotelnikov IREE RAS by the author.
