Abstract
The method for controlling the shape of antenna patterns using the Fresnel zones fragmentation is suggested. Measurements of the horn and the helical antenna patterns are performed. Amplitude distributions of field components are obtained and analyzed in the near, intermediate and far zones for different frequency bandwidths. 3D images of the intensity, the angle and the radii for the far and near zones are built based on the experimental results.
