В структуре современных гибких отражательных антенных решеток в качестве проводящего материала используются металлы. Графен обладает уникальными свойствами, которые подходят для гибких антенных систем, - механическая устойчивость, низкая удельная масса и стоимость. В работе впервые рассмотрена возможность использования графена в качестве проводящего материала в конструкции единичных элементов отражательной антенной решетки ГГц-диапазона: микрополоскового элемента, микрополоскового элемента с кольцом и микрополоскового элемента с линией задержки. Минимальные значения амплитуды падающей волны и диапазон изменения фаз для каждого элемента составил -4.08 дБ и 327.6 градусов, -19.63 дБ и 684.73 градусов, -6.24 дБ и 526 градусов соответственно. Проведено сравнение полученных характеристик единичных элементов с аналогичными серебряными элементами. Сравнение характеристик с аналогами показало, что графеновые единичные элементы ОАР обладают удовлетворительными характеристики.</p></abstract><trans-abstract xml:lang="en"><p>Flexible reflectarrays are widely used as deployable antennas in the design of small satellites (weight about 320 kg) to reduce the weight and size characteristics. Modern flexible reflectar-ray antenna use metals as the conductive material. Graphene has unique properties that are suitable for flexible antenna systems - mechanical stability, low specific gravity and cost. This paper is the first to consider the possibility of using graphene as a conductive material in the design of unit cell elements of a reflectarray antenna in the GHz range: a patch element, a patch element with a ring, and a patch element with a delay line. The minimum values of the incident wave amplitude and the phase variation range for each element were -4.08 dB and 327.6 degrees, -19.63 dB and 684.73 degrees, -6.24 dB and 526 degrees, respectively. The comparison of the obtained characteristics of unit cell elements with similar silver elements is carried out. Comparison of the characteristics with the literature analogs showed that the graphene unit cell elements of the reflectarray antenna have satisfactory characteristics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>отражательная антенная решетка</kwd><kwd>графен</kwd><kwd>гибкая электроника</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reflectarray antenna</kwd><kwd>graphene</kwd><kwd>flexible electronics</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">Chandra A. et al.
