SOFTWARE IMPLEMENTATION OF THE CALCULATION OF THE FRAME ANTENNAS FIELD SPATIAL DISTRIBUTION

Abstract

An antenna is an integral part of any radio device designed to transmit or receive information using radio waves through the surrounding space. Investigations of the energy, phase and polarization characteristics of electromagnetic fields near industrial systems may be of great importance not only from a scientific point of view, but also for a wide variety of technical problems. Relevant is the task of structural prediction and instrumental control of the level of electromagnetic fields near the antennas for the purpose of ensuring electromagnetic safety. The problem of analyzing the characteristics of electromagnetic compatibility of closely located antennas, in particular, the calculation of protective screens, other theoretical and practical tasks, is of great importance. When solving problems of electromagnetic compatibility, the structure of the field in the near zone of the antenna, its directional characteristics, levels of lateral radiation, as well as determination of values of electric and magnetic fields are of particular interest. The near fields of electromagnetic emitters have a complex spatial structure, therefore the theoretical analysis of wave processes near such emitters is possible only through computer modeling of emitters with specified dimensions at a specified wavelength. The widespread use of frame wire antennas necessitates the development of new approaches and methods for researching their spatial characteristics. The purpose of the publication is the software implementation of the calculation of the spatial values of the magnetic induction vector of frame antennas. An analytical method of studying the spatial characteristics of the near field of frame antennas is considered, which can be used in the synthesis of systems in which frame antennas are used, and in conducting scientific research in the field of information technology, technical information protection, when solving problems of electromagnetic compatibility of technical systems. The use of software for calculating and visualizing the magnetic field allows you to analyze in detail the spatial distribution of the magnetic field of frame antennas.
