Отражательные антенные решетки (ОАР) обладают рядом конструктивных и функциональных преимуществ относительно ближайшего аналога – зеркальных антенн (ЗА). Наиболее предпочтительными элементами ОАР являются микрополосковые, однако однослойные микрополосковые элементы зачастую не позволяют точно скорректировать фазу в ОАР из-за ограниченного диапазона фазовой регулировки и высокой крутизны фазовой кривой. Использование многослойных элементов заметно усложняет и удорожает конструкцию антенны. В связи с этим актуален поиск однослойных элементов, обеспечивающих фазовую регулировку более 360° с малой крутизной фазовой кривой.Цель работы. Разработка однослойного микрополоскового фазокорректирующего элемента отражательного типа с диапазоном регулировки более 360° и создание на его основе ОАР для работы в сетях спутниковой связи.Материалы и методы. Численные исследования проведены методом конечных элементов и методом конечных разностей во временно́й области. Характеристики направленности измерялись сканированием ближнего поля в безэховой камере.Результаты. Разработан фазокорректирующий элемент на основе однослойного микрополоскового резонатора в виде мальтийского креста с близкой к линейной зависимостью фазы отраженной волны от размера элемента, обеспечивающий диапазон фазовой регулировки более 360°. На основе исследованного элемента разработана и изготовлена разборная конструкция ОАР, в которой рефлектор состоит из четырех подрешеток, что обеспечивает компактное свертывание ОАР для транспортировки. Результаты экспериментальных исследований показали высокую эффективность ОАР, коэффициент усиления (КУ) которой на 1.5 дБ ниже КУ ЗА идентичных габаритных размеров в относительной полосе рабочих частот (ОПРЧ) 7 %. ОПРЧ ОАР по уровню снижения КУ на 1 дБ составила 11 %.Заключение. На основе элемента в виде мальтийского креста возможна реализация однослойных ОАР с ОПРЧ более 10 %. Разработанный макет показал возможность создания высокоэффективных сворачиваемых ОАР для работы в составе терминалов спутниковой связи и телевидения.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Reflectarrays have a number of design and functional advantages over their closest analogue - reflector antennas (RA). Although microstrip elements are the most preferred reflectarray elements, single-layer microstrip elements do not allow accurate phase control due to the limited phase adjustment range and a high phase slope. The use of multilayer elements significantly complicates the antenna design and increases its cost. The development of a single-layer element that allows more than 360° phase adjustment and a low phase curve slope is urgent.Aim. To develop a single-layer microstrip phase-correcting element with a phase adjustment range of more than 360° and to design a reflectarray on its basis for operation in satellite communication networks.Materials and methods. Numerical studies were carried out using finite element analysis and the finite-difference time-domain method. Radiation patterns were measured using the near-field scanning method in an anechoic chamber.Results. A phase-correcting element based on a single-layer Maltese cross-shaped microstrip element with close to linear dependence of element size on the phase of the reradiated wave and more than 360° phase adjustment range was developed. On the basis of the investigated element, a foldable reflectarray was designed. The reflector consists of four subarrays, which provide its compact folding for transportation. The results of experimental studies confirmed a high efficiency of the reflectarray, the gain of which is 1.5 dB lower than that of an identical overall dimensions RA in a 7 % operating frequency band. The operating frequency band of the reflectarray in 1 dB gain zone was 11 %.Conclusion. On the basis of a Maltese cross microstrip element, it is possible to implement a single-layer reflectarray with a more than 10 % frequency band. The developed prototype showed the possibility of creating highly efficient foldable reflectarrays for operation in satellite communication and television terminals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>отражательная антенная решетка</kwd><kwd>ячейка Флоке</kwd><kwd>микрополосковый элемент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reflectarray</kwd><kwd>Floquet cell</kwd><kwd>microstrip element</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено при финансовой поддержке РФФИ, Правительства Красноярского края и Красноярского краевого фонда науки в рамках научного проекта № 20-47-240003.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was funded by RFBR, Krasnoyarsk Territory and Krasnoyarsk Regional Fund of Science, project number 20-47-240003.</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">A Ku-band foldable reflectarray / S.
