Annotation

A dipole wire antenna of the Koch type is considered. The antenna represents a wire dipole symmetrical with respect to the point of feeding. Arms of the dipole have a geometry similar to Koch's prefractal. The curves forming the arms differ from the classical Koch fractal only by the position of the central vertex. A family of antennas is singled out, in which the antennas differ from each other by coordinates of the central vertices. An algorithm for calculating lacunarity is described. A paired correlation analysis is provided for the reflection coefficient, reactance, resistance and lacunarity. Antennas having the geometry of the first three iterations of a Koch-type curve are chosen for the analysis. The calculated correlation coefficients are given in the tables. It is shown that an increase in iteration leads to a decrease in the correlation between the electrodynamic parameters and lacunarity. It is obtained that the best correlation with lacunarity has the reactance. Singleparameter regression models for the considered electrodynamic characteristics are constructed. The root-mean-square errors for the models are calculated. The proposed regression formulas can be used for the initial design of well-matched wire antennas
