Для реализации излучения предлагается конструкция на основе радиального волновода и спиральных антенных элементов, обладающих круговой поляризацией. Для формирования вихревого излучения применяется механический поворот антенных элементов вокруг их оси для реализации фазового сдвига. На основании приведенной конструкции приводится анализ формирования вихревых волн первых двух мод в широком диапазоне волн. В работе приведены характеристики вихревых волн, а также их формирование в зависимости от диапазонов рабочих частот антенной решетки. Приведенные результаты показывают возможность формирования вихревых волн в широком диапазоне частот на основании применения кольцевой антенной решетки с системой возбуждения на основе радиального волновода.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents an antenna design that enables the generation of vortex waves or waves with orbital angular momentum of the first two modes over a wide wavelength range. To implement the radiation, a design based on a radial waveguide and circularly polarized helical antenna elements is proposed. To generate vortex radiation, mechanical rotation of the antenna elements around their axis is used to create a phase shift. Based on this design, an analysis of the generation of vortex waves of the first two modes over a wide wavelength range is presented. The paper presents the characteristics of vortex waves, as well as their generation depending on the operating frequency ranges of the antenna array. The presented results demonstrate the possibility of generating vortex waves over a wide frequency range using a ring antenna array with an excitation system based on a radial waveguide. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>вихревые волны</kwd><kwd>орбитальный угловой момент</kwd><kwd>OAM</kwd><kwd>широкополосная связь</kwd><kwd>радиальный волновод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vortex waves</kwd><kwd>orbital angular momentum</kwd><kwd>OAM</kwd><kwd>broadband communications</kwd><kwd>radial waveguide</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках государственного задания "молодежная лаборатория" № FZGM-2026-0006.</funding-statement><funding-statement xml:lang="en">This work was supported by the Ministry of Science and Higher Education of the Russian Federation under the state assignment "Youth Laboratory" No. FZGM-2026-0006.</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">Jha P., Wu K.
