Рассмотрены различные варианты включения отрицательной индуктивности в структуру рамочной антенны. Получено аналитическое предельное соотношение для рабочей полосы частот рамочной антенны при включении отрицательной индуктивности в разрыв проводника рамки. Показано, что для практической реализации наиболее удобной является схема с включением отрицательной индуктивности между проводящей плоскостью и свободным выводом рамки. При таком включении нефостеровского элемента существует небольшой проигрыш в ширине рабочей полосы частот по сравнению с включением этой индуктивности в разрыв проводящей плоскости рамки, однако в 2 раза выше наводимая в рамке ЭДС. Получено интегральное выражение для максимальной полосы согласования рамочной антенны при включении отрицательной индуктивности у заземленного вывода, интеграл в котором вычислялся численно для различных добротностей рамочной антенны и соотношений между резонансной частотой рамки и рабочим диапазоном частот. Полученные результаты подобны ограничению Фано–Юлы для пассивных согласующих цепей.</p></abstract><trans-abstract xml:lang="en"><p>The limiting characteristics of electrically small-sized loop antenna matching by means of non-Foster's negative inductance are studied. Various options for including negative inductance in frame antenna structure are considered. The analytical limit expression for the operating frequency band of the small-sized loop antenna with the inclusion of negative inductance in the gap of the conductor frame is obtained. It is shown that for practical implementation the most convenient is the scheme with the inclusion of negative inductance between the conducting plane and the free output of the frame. Such inclusion of negative inductance causes small loss in width of the working frequency band compared with the inclusion of this inductance in the gap of the frame conductive plane, but EMF induced in the frame is twice as large.  An integral expression is obtained for the maximum band matching of the small-sized loop antenna with the inclusion of negative inductance in grounded output, the integral in which is calculated numerically for various small-sized loop antenna quality factor and ratios between resonant frequency of the frame and operating frequency range. The results obtained are similar to Fano-Yula restriction for passive matching chains.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>согласование</kwd><kwd>добротность</kwd><kwd>электрически малая антенна</kwd><kwd>нефостеровские элементы</kwd><kwd>конвертор отрицательного импеданса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Matcging</kwd><kwd>Q-factor</kwd><kwd>Electrically Small Antenna</kwd><kwd>Non-Foster Elements</kwd><kwd>Negative Impedance Converter</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">Sussman-Fort S.
