Karazin Kharkiv National University popup.description2  Object of study - physical phenomena and radiation conditions, focusing, diffraction and interference electromagnetics waves by antenna arrays. Purpose of the study - solution to a fundamental problem of physics of radiation systems - synthesis of ultra-direction antenna arrays with specified directional characteristics by modern methods of applied and computational mathematics. Research methods - theoretical research, computer analysis and experiment. Mathematical software, algorithm and computer programs of calculation the amplitude, phase and polarizing radiation characteristics of linear continuous antennas that were synthesized by radiation pattern that was given in analytical form have been developed The task of diffraction of resonant vibrator radiation on the perfectly conductive screen with rectangular or square form was solved. By computer experiment was proved that such vibrator antennas allow to form radiation patterns of sector shape. Range properties of vibrator antenna with flat screen final size were researched. Mathematical support for calculation, analyses and constructional synthesis of radiation of equidistant antenna array on any distance from them. Product Description popup.authors Elisieieva Nadiia P.
