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%.

Key words: microstrip line, miniaturization, Butler matrix.
