Перестройка осуществляется с помощью переменного конденсатора с цифровым управлением. Антенну перестраивают на один из четырех низкочастотных диапазонов, при этом сохраняя настройку на высокочастотный диапазон. Компьютерное моделирование антенны проведено с помощью программы RFS. </p></abstract><trans-abstract xml:lang="en"><p>First results of the development of a tunable antenna for cellular phones operating in the standard LTE are presented. The antenna consists of high- and low-frequency branches, the latter one is tuned by digital-controlled capacitor. Computer simulation of the antenna was conducted by using the RFS. Simulation results show that low-frequency antenna branch can be tuned without detuning high-frequency one. Radiation efficiency of the antenna in high-frequency band yields 60 % or more, while in low-frequency range efficiency drops to 20…30 %. The work on improving these results is now continuing. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Антенна</kwd><kwd>сотовый телефон</kwd><kwd>переменный конденсатор</kwd><kwd>компьютерное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Antenna</kwd><kwd>smartphone</kwd><kwd>variable condenser</kwd><kwd>computer simulation</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">Kivakas O., Ollikainen J., Vainikainen P.
