Abstract
The article discusses various schemes for constructing antenna systems with wide-angle scanning in the azimuth plane for a ground communication system. It is shown that antennas with spatial arrangement of elements allow increasing the gain. The directivity and frequency characteristics of such antennas are determined. It is shown that at small sizes of the equivalent aperture, there is a small difference in the energy parameters. Preliminary calculations of various schemes for constructing antenna arrays with wide-angle scanning have been carried out. The element base for the manufacture of radiators of a cylindrical antenna array has been determined. Electrodynamic models of microstrip dipole radiators operating in the 9% band have been developed. Parametric optimization of such antennas is performed. A technique for calculating the elements of the antenna array has been developed. The directivity characteristics of dipole radiators and antenna arrays of two elements that make up the sub-array of cylindrical active phased antenna arrays are determined. The influence of the mounting frame on the directivity and matching characteristics is shown. The sublattice design has been optimized to achieve the required matching. A model of a cylindrical antenna array has been developed. Issues of beam formation and control are considered. The characteristics of the directivity and matching of the cylindrical antenna array are determined, considering the influence of the fastening elements and the radome.
