The paper consideres a complex method of accounting for the influence of radiation patterns on electromagnetic compatibility and accessibility of wide nomenclature range of antennas of the general-purpose electronic systems. Simulation results are given.
The paper addresses new results of research on the use of an accelerating lens to increase throughput, range and noise immunity of exchange in a certain priority direction in the system of wireless access of IEEE 802.11 standard. Compared with previous works, efforts have been focused on solving these problems as applied to the MIMO systems, in which a problem emerges to choose an all-purpose lens...
The mathematical and physical models of the process of excitation of a slotted broadband antenna are proposed. The results of theoretical and experimental studies of the electrodynamic properties of a cone with longitudinal slots are obtained. Calculated diagrams of the spatial field distribution with the experimentally measured data are compared.
This paper describes a new method proposed for obtaining a special form radiation pattern. The main idea of this method is to use a combination of straight and incline diffraction gratings in a planar diffraction radiation antenna. A comparison of radiation characteristics of straight and inclined gratings was made. The radiation pattern of antenna with a combined grating confirms the correctness...
The algorithm of linear antennas array radiation pattern formation for shipboard radar is proposed, which, at the cost of tuning two antenna array elements only, provides practically full suppression of side lobes of the array radiation pattern (RP) at any azimuth angle beyond the main lobe area. This gives the possibility of separated surveillance of signals from vessels with large and small target...
The results of experimental research of low-cost ultrawideband antennas composed of printed basic elements are presented. Photos of the antennas are shown. Diagrams of the spatial field distribution are investigated.
