Abstract
In the following work the results of the researches of the directional properties of multiring radiating antennas which rings coincide with Fresnel regions are presented. The zone antenna is investigated at blocked second, fourth, sixth Fresnel regions, and also with phase invertors in these zones. The algorithm of calculation of the radiation patterns of multiring antennas with arbitrary amplitude-phase distribution is given. Similarity of theoretically and experimentally obtained radiation patterns of the developed type of zone antenna is shown.
