Антенные решетки сильносвязанных диполей в настоящее время относятся к одному из наиболее востребованных типов систем излучателей. Их основные достоинства – электрически малая высота профиля, возможность сканирования луча в широком секторе углов без появления эффекта ослепления, низкий уровень кроссполяризации. Количество публикаций по теме антенных решеток этого типа за последние годы значительно выросло. Большое внимание авторы уделяли симметрирующим устройствам в составе излучателей. Однако малоизученной остается возможность реализации простого дифференциального питания плеч диполей в антенных решетках такого типа, что делает исследование этого вопроса особенно актуальным при разработке радиотехнических устройств, где такая схема питания является предпочтительной.</p></sec><sec><title>Цель работы</title><p>Цель работы. Разработать конструкцию элемента антенной решетки сильносвязанных дипольных излучателей с дифференциальным питанием и исследовать ее характеристики.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для изготовления макета применялись следующие материалы: лист медный, диэлектрик RO3003, ситалловая подложка СТ-50-1. Численное исследование характеристик выполнялось в программе ANSYS HFSS, экспериментальное исследование макета – в безэховой камере с применением автоматизированного измерительного комплекса и векторного анализатора цепей.</p></sec><sec><title>Результаты</title><p>Результаты. Представлены результаты проектирования плоской антенной решетки сильносвязанных диполей X-диапазона. В антенной решетке питание каждого из плеч диполей осуществляется при помощи отдельного коаксиального кабеля, при этом 2 плеча одного диполя запитываются в противофазе. Приведены результаты численного исследования характеристик антенной решетки 8 × 8 из разработанных элементов. В диапазоне от 6.5 до 12.25 ГГц средний активный коэффициент стоячей волны по напряжению не превышает 3, при этом коэффициент усиления варьируется от 21.5 до 25.7 дБи. Показана возможность сканирования луча в секторе углов до ±45°. Приведены результаты экспериментального исследования характеристик излучения и согласования макета одного элемента.</p></sec><sec><title>Заключение</title><p>Заключение. Показана важность проведения расчетов с учетом эффектов, возникающих на краях антенных решеток конечных размеров. Экспериментально подтверждена целесообразность изготовления и измерений макетов антенных решеток с большим количеством элементов. Предложенная конструкция элемента показала возможность реализации дифференциального питания в антенных решетках сильносвязанных дипольных излучателей.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Tightly coupled dipoles currently belong to one of the most popular types of antenna arrays. Their main advantages include an electrically low-profile height, the ability to scan the beam across a wide sector of angles without the onset of scan blindness, and a low level of cross-polarization. In recent years, the number of publications on the topic of antenna arrays of this type has increased significantly. The authors have paid sufficient attention to baluns included in the antenna array elements. However, the possibility of implementing a differentially-fed scheme in antenna arrays of this type remains poorly studied. This makes the study of this subject especially relevant in the development of radio devices where such feed technique is preferable.</p></sec><sec><title>Aim</title><p>Aim. Differentially-fed tightly-coupled dipole array design and study.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The following materials were used to create the prototype: copper sheet, ceramic glass substrate ST-50-1, dielectric RO3003. A numerical study of the characteristics was carried out in the ANSYS HFSS environment; an experimental study of the prototype was carried out in an anechoic chamber using an automated measuring complex and a vector network analyzer.</p></sec><sec><title>Results</title><p>Results. The results of designing a planar antenna array of tightly-coupled dipoles for the X-band are presented. In the antenna array, each of the dipole arms is fed using a separate coaxial cable, while the two arms of one dipole are fed out-of-phase. The results of a numerical study of the characteristics of an 8 × 8 antenna array made from the developed elements are presented. Across the range from 6.5 to 12.25 GHz, the average active VSWR does not exceed 3, while the gain varies from 21.5 to 25.7 dBi. The possibility of beam scanning in a sector of angles up to ±45° is shown. The results of an experimental study of the radiation characteristics and matching of the prototype of a single element are presented.</p></sec><sec><title>Conclusion</title><p>Conclusion. The importance of taking into account the effects that arise at the edges of finite antenna arrays during simulations is shown. The feasibility of manufacturing and measuring antenna array prototypes with a large number of elements is experimentally confirmed. The proposed element design demonstrates the possibility of implementing the differentially-fed scheme in tightly coupled antenna arrays.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>антенные решетки</kwd><kwd>взаимная связь</kwd><kwd>дипольные антенны</kwd><kwd>дифференциальное питание</kwd><kwd>ССДИ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antenna arrays</kwd><kwd>mutual coupling</kwd><kwd>dipole antennas</kwd><kwd>differential feed</kwd><kwd>TCDA</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Opportunities and advances in ultra-wideband electronically scanned arrays / J.
