 В статье рассматривается реализация направленных ответвителей в микрополосковой линии, предназначенной для линий связи в диапазоне частот 2‒3 ГГц, на подложке из широко используемого и общедоступного материала RO4350, с коэффициентом связи 3‒7 дБ. Эти направленные ответвители были разработаны с учетом дополнительных граничных условий для уменьшения габаритных размеров устройства. В ходе численного моделирования уточнялись поправочные коэффициенты, использованные для предварительных аналитических расчетов. Данные численного эксперимента были проверены при помощи измерений макета. 

 The article discusses the implementation of directional couplers in a microstrip line, designed for communication lines in the frequency range of 2‒3 GHz, on a substrate made of a widely used and generally available material RO4350, with a coupling factor of 3‒7 dB. These directional couplers have been designed with additional boundary conditions to reduce the size of the device. In the course of numerical modeling, the correction factors used for preliminary analytical calculations were refined. The data of the numerical experiment were verified using the measurements prototype model.
