Karazin popup.description2 The object of study - the processes of formation of multi-beam patterns in highly directional antenna systems. The purpose of research - development of electrodynamic theory and numerical and analytical methods for solving problems of radiation, that is, the external problems of electrodynamics, multipath highly directional reflector antennas and antenna arrays dipole, microstrip, waveguide and horn omnidirectional radiators working at the two orthogonal linear polarizations. On the basis of the aperture ray method developed mathematical models of single and multiple illuminators of the open ends of square and round waveguides and pyramidal and conical horns, running on two orthogonal linear (vertical and horizontal) polarizations. Methods of the geometric theory of diffraction of a mathematical model of group two polarization vibrator and microstrip feed multibeam reflector antenna located on a perfectly conducting screen square shape. The conditions under which the proposed sources provide near-rotationally symmetric shape of the main lobe. The mathematical models are applicable throughout the front half. Current methods of physical diffraction theory developed mathematical models of spherical parabolic and highly directional multibeam reflector antennas. It is shown that an increase in the angle of deviation from the normal pattern of partial directional characteristics deteriorate. The characteristics of the two polarized multibeam multiband offset reflector antennas are calculation. Studied theoretically near field antenna aperture mirror size and large electrical field in the focal region of the antenna aperture with quadratic phase distributions.
