Предложены методы расширения рабочей полосы частот устройства. Представлена конструкция реконфигурируемого ответвителя с возможностью изменения типа направленности с сонаправленного на противонаправленный и наоборот, благодаря включению в состав разомкнутого кольцевого резонатора полупроводникового варикапа. </p></abstract><trans-abstract xml:lang="en"><p>The original design approach for 0-dB directional coupler with forward and backward coupling in two different frequency bands is proposed. The device is realized by loading the coupled line based directional coupler by split ring and mushroom resonators. Under discussion is the reconfigurable directional coupler with control of the type of directivity from forward to backward one and vice versa, provided by changing the capacitance of the varactor, inserted into the gaps of split ring resonators. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Направленный ответвитель</kwd><kwd>направленность</kwd><kwd>управляемость</kwd><kwd>гальваническая развязка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Directional coupler</kwd><kwd>directivity</kwd><kwd>control</kwd><kwd>DC blocking</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">Сазонов Д.
