KOCH FRACTAL DIPOLE MATCHING BY TURNING OF THE ARMS

A dipole wire antenna of the Koch is considered. The antenna represents a wire dipole symmetrical with respect to the point of feeding. Arms of the dipole have the geometry of Koch prefractal. A family of antennas is singled out, in which the antennas differ from each other by an angle of arms turning. Antennas having the geometry of the first two iterations of a Koch curve are chosen for the analysis. Dipoles based on the Koch pre-fractals of the first two iterations having different wire thicknesses obtained by rotating one of the arms around a given coordinate axis is considered. Graphs depicting dependence of the reflection coefficient at the base frequency on angles of rotation around the axes are presented. Resonance angles of rotation of a "perfectly my" matched antenna's arms are obtained. A conclusion is drawn on possibility of significant improvement of antenna matching by turning the dipole arms with respect to each other.
