Ряд работ в области конструирования антенн Фабри–Перо направлен на достижение широкой полосы рабочих частот, однако не всегда удается добиться сравнительно одинакового коэффициента усиления внутри нее. В данной статье описана конструкция антенны Фабри–Перо, в которой для расширения полосы частот использовалась перестраиваемая щелевая антенна. Одним из критериев при разработке антенного устройства являлась высокая стабильность коэффициента усиления – его изменения не должны превышать 1 дБ в заявленной полосе.</p></sec><sec><title>Цель работы</title><p>Цель работы. Разработка антенны Фабри–Перо для частотного диапазона 4.9…5.5 ГГц с высокой стабильностью коэффициента усиления внутри рабочей полосы частот.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В конструкции разрабатываемой антенны в качестве перестраиваемых элементов использовались тонкопленочные сегнетоэлектрические конденсаторы. Диэлектрическим материалом при разработке антенны служил металлизированный армированный фторопласт. Параметры сегнетоэлектрических элементов измерялись с использованием резонансной методики, в то время как параметры диэлектрического материала определялись с помощью метода Николсона–Росса–Вейра.</p></sec><sec><title>Результаты</title><p>Результаты. Рабочая полоса частот разработанной антенны составила 4.9…5.5 ГГц. Были изготовлены и экспериментально исследованы образцы сегнетоэлектрических конденсаторов и фольгированного диэлектрического материала, на основе которых был создан прототип перестраиваемой щелевой антенны. Результаты моделирования показали, что коэффициент усиления разработанной антенны Фабри–Перо составил не менее 10 дБ.

Разработана Антенна Фабри–Перо на основе электрически перестраиваемой щелевой антенны и двухслойной частотно-селективной поверхности. Рабочая полоса частот разработанной антенны составила 4.9…5.5 ГГц, что соответствует полосе частот сетей Wi-Fi. Оптимизация конструктивных параметров антенны позволила добиться высокого коэффициента усиления при его малом изменении в заданном частотном диапазоне.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. One of the directions in Fabry–Perot antenna design consists in increasing its operation frequency range. In the present work, we set out to develop a Fabry–Perot antenna with a smooth gain pattern across a wide frequency range. To that end, a tunable slot antenna based on a thin-film ferroelectric varactor was used. The major development criterion was a high uniformity of the gain pattern, not exceeding 1 dB in the given frequency band. Aim. To develop a Fabry–Perot antenna for the 4.9–5.5 GHz frequency range with a high gain uniformity within the operating frequency band.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The antenna under development was based on thin-film ferroelectric capacitors as tunable elements. Fluoroplastic plates metallized on both sides were used as a dielectric material for manufacturing a frequency selected surface and a slot antenna. The parameters of ferroelectric elements were measured using a resonance technique, while the parameters of the dielectric material were determined using the Nicholson–Ross–Weir method.</p></sec><sec><title>Results</title><p>Results. The developed antenna has an operating frequency band of 4.9–5.5 GHz. Samples of ferroelectric capacitors and foiled dielectric material were manufactured and experimentally investigated. A tunable slot antenna was fabricated, and its characteristics were measured. The simulation results show that the gain value of the developed Fabry–Perot antenna is not less than 10 dB in the operation frequency range. Variations in the gain value within the operating frequency band do not exceed 0.7 dB.</p></sec><sec><title>Conclusion</title><p>Conclusion. A Fabry–Perot antenna based on an electrically tunable slot antenna and a two-layer frequency-selective surface was developed. The operating frequency band of the developed device ranges within 4.9–5.5 GHz, which corresponds to the frequency band of Wi-Fi networks. Optimization of the antenna design parameters made it possible to achieve higher gain values under their minor variations in the operation frequency band.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>антенна Фабри–Перо</kwd><kwd>щелевая антенна</kwd><kwd>сегнетоэлектрический конденсатор</kwd><kwd>фольгированный ламинат</kwd><kwd>политетрафторэтилен</kwd><kwd>тонкая пленка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Fabry–Perot antenna</kwd><kwd>slot antenna</kwd><kwd>ferroelectric capacitor</kwd><kwd>foiled laminate</kwd><kwd>polytetrafluoroethylene</kwd><kwd>thin film</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено в рамках Государственного задания № 075-01438-22-07 от 28.10.2022 г.
