Karazin Kharkiv National University popup.description1 The purpose of the work is to study the practically important features of the formation of electromagnetic fields by radiating structures, antennas and antenna arrays based on combined radiating elements with impedance, magnetic (slot), electric (vibrator), magnetic-electric, microstrip radiators (multi-channel, multi-frequency combined waveguide-slot, vibrator-slot antenna arrays), modified leaky-wave antennas; substantiation of the possibility of controlling their directional and polarization characteristics on the basis of physically adequate and mathematically correct modeling; optimization of functional (frequency-energy, polarization, frequency-spatial) characteristics, minimization of the weight and size parameters of radiating structures for radio-electronic systems for various purposes (mobile communication systems, radar, electronic warfare, etc.) and basing conditions, solving problems to improve their noise immunity and ensure electromagnetic compatibility. popup.description2 The object of research is the physical phenomena and processes of excitation, radiation, and formation of electromagnetic fields by multi-element, multi-resonant, multi-frequency, multifunctional combined structures with slot, vibrator, vibrator-slot (including impedance), and microstrip radiating structures, as well as antenna arrays and leaky-wave antennas. The aim of the work is to study the features of electromagnetic field formation by new combined radiating structures, antennas, and antenna arrays with scattering elements of various types and arbitrary topology that form components of multi-element radiating systems; to optimize their electrodynamic (functional) characteristics and justify the possibility of controlling them; and to minimize the weight and size parameters of radiating structures for radio electronic systems (mobile communication systems, radar systems, electronic warfare systems, etc.). Mathematical models were developed, and computer calculations and simulations were carried out for multi-element, multi-frequency equidistant and non-equidistant antenna arrays, as well as multichannel arrays with a combined aperture and combined radiating elements, including those with impedance properties, based on a multimode rectangular waveguide. An efficient algorithm was developed and implemented for calculating leaky-wave radiators formed by a planar dielectric waveguide and a comb structure. The eigenmode spectrum of a three-dimensional model of a real clinotron slowing-wave system was determined. Microstrip antennas and antenna arrays with linear and circular polarization at an operating frequency of 5.8 GHz were developed based on radiators in the form of open rings and linear electric-type elements, adapted for direction finding of FPV drones and promising for UAV applications. Their use ensures high efficiency of signal transmission and reception and strong resistance of radio electronic systems to external electromagnetic interference.
