Abstract

An approach to miniaturization of a 4x4 Butler matrix assembled on compact two-loop bridges with an operating frequency of 1 GHz is investigated. The miniaturization procedure itself consists in simply replacing the quarter-wave segments with compact structures. Using the program, such structures were obtained for the desired characteristics. The proposed Butler matrix was fabricated and measured. The die area has been reduced by 55%.

Миниатюризация матрицы Батлера 4х4

Исследован подход в миниатюризации матрицы Батлера 4х4, собраннойя на компактных двухшлейфных мостах с рабочей частотой 1 ГГц. Сама процедура миниатюризации заключается в простой замене четвертьволновых отрезков на компактные структуры. С использованием программы были получены такие структуры под нужные характеристики. Предложенная матрица Батлера была изготовлена и промерена. Площадь матрицы была уменьшена на 55%.
