Представлены сравнительные результаты электродинамического моделирования и натурных измерений в безэховой камере опытного образца печатной 8-лучевой фазированной антенной решетки на основе матрицы Батлера. Приведена математическая модель модифицированного дифференциального фазовращателя, защищенного патентом Российской Федерации и характеризующегося наибольшей на сегодняшний день широкополосностью. Предложена и охарактеризована топология инновационного излучателя дипольного вида с концевым питанием. Цель работы. Проектирование на основе системного подхода 8-лучевой антенной решетки, моделирование ее основных электродинамических характеристик и сравнение с результатами натурных экспериментов. Материалы и методы. В качестве методов для проектирования электродинамических моделей элементов и узлов диаграммообразующей схемы, а также излучателя используются метод наводимых электродвижущих сил, математические основы проектирования микрополосковой техники, процедуры электродинамического моделирования элементов и узлов микроволновой техники и СВЧ-устройств. В качестве материалов служит отечественный диэлектрический материал ФАФ-4Д с относительной диэлектрической проницаемостью 2.5. Результаты. Экспериментально получены характеристики согласования и направленности 8-лучевой антенной решетки, и осуществлено их сравнение с результатами полноволнового электродинамического моделирования. В результате в полосе частот 2.02…2.37 ГГц наблюдается приемлемое совпадение измеренных и смоделированных результатов по положениям лучей, интенсивностям кроссполяризации, коэффициентам отражения и развязке между входами матрицы Батлера – не хуже –15 дБ. Заключение. Проектирование и финальная доработка фазированных антенных решеток с улучшенными электродинамическими характеристиками при учете отечественных конструкторско-технологических норм и требований позволит создать предпосылки для качественного увеличения тактико-технических показателей приемопередающих устройств в целом, а также системно отработать процедуры синтеза таких решеток и их отдельных узлов.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. This paper presents comparative results of electrodynamic modeling and field measurements in an anechoic chamber of a prototype of a printed eight-beam phased antenna array based on the Butler matrix. A mathematical model of a modified differential phase shifter protected by a patent of the Russian Federation and characterized by the highest broadband to date is presented. The topology of an innovative dipole-type radiator with end feeding is proposed and characterized. Aim. To design an eight-beam antenna array based on a systems approach, to model its main electrodynamic characteristics, and to compare them with the results of full-scale experiments. Materials and methods. Electrodynamic models of elements and units of the diagram-forming circuit, as well as the emitter, were designed using the method of induced electromotive forces, mathematical foundations of designing microstrip-technologies, procedures for electrodynamic modeling of elements and units of microwave technology and microwave devices. The FAF-4D domestic dielectric material with a relative permittivity of 2.5 was used. Results. The characteristics of the matching and directivity of the eight-beam antenna array were obtained followed by their comparison with the results of full-wave electrodynamic modeling. As a result, in the frequency band of 2.02…2.37 GHz, an acceptable coincidence of the measured and modeled results is observed for the positions of the beams, cross-polarization intensities, reflection coefficients, and decoupling between the Butler matrix inputs of no worse than 15 dB. Conclusion. The design and final refinement of phased antenna arrays with improved electrodynamic characteristics, taking domestic design and technological standards into account, will form a basis for a qualitative increase in the tactical and technical performance of transceiver devices as a whole, allowing procedures for synthesizing such arrays and their individual units to be developed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фазированная решетка</kwd><kwd>многолучевой режим работы</kwd><kwd>матрица Батлера</kwd><kwd>диаграмма направленности</kwd><kwd>коэффициент отражения</kwd><kwd>кроссполяризация</kwd><kwd>технология печатных плат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>phased array</kwd><kwd>multi-beam mode</kwd><kwd>Butler matrix</kwd><kwd>radiation pattern</kwd><kwd>reflection coefficient</kwd><kwd>crosspolarization</kwd><kwd>printed circuit board technology</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 24-29-20048 (https://rscf.ru/project/24-29-20048/), а также при финансовой поддержке Правительства Новосибирской области, соглашение № р-77.</funding-statement><funding-statement xml:lang="en">The study was supported by the grant of the Russian Science Foundation No. 24-29-20048 (https://rscf.ru/project/24-29-20048/), as well as with the financial support of the Government of the Novosibirsk Region, agreement No. p-77.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Handbook of Antenna Technologies.
