Abstract
The variety of fractal curve types opens up additional structural and electrodynamic possibilities in the design of antennas. The article describes experimental results of studying characteristics of different types of fractal antennas (fractal triangular Koch antenna, fractal square Koch antenna and anisotropic fractal antenna). These types of curves are extreme cases in the direction of deformation of fractals. In this paper, we propose a new dual band wire dipole antenna based on an anisotropic fractal. We obtained the frequency reflection coefficients and the radiation patterns at the resonance frequency of each antennas at the second iteration (n = 2). We made an analysis of the parameters of each antenna. It is shown that a half-wave vibrator configured on the base of the original anisotropic fractal has a maximum effective capture area. The Computer Simulation Technology High Frequency Structural Simulator (HFSS) software was used to design and analyze the antenna. Computed bandwidths are 0.2 to 2.7 GHz. This bandwidth covers the IEEE 802.11.
