Investigation of the electrodynamic characteristics of fractal double-ring antenna

The electrodynamic parameters of fractal double-ring antennas are presented in the article. The design of these antennas is based on the topology of circular fractal lakes. The frequency dependences of the input impedance, the standing wave coefficient, and the directional properties of two-ring antennas are calculated and analyzed. Calculations of the characteristics, produced by numerical simulation, allow one to see the influence of the scale factor of the rings on the broadband characteristics of the antennas.
