Abstract—In this letter, a novel approach to the design of a commonly known branch line directional couplers is presented for operation in a differential mode. The couplers are analyzed in a two-mode structure and realized in a symmetric two-conductor-over-ground transmission line technique. Moreover, the investigation on the possible miniaturization of such circuits is presented. The results of theoretical analysis are verified by the measurement of the fabricated circuits.

Index Terms—Balanced-mode components, directional couplers, branch-line couplers, miniaturized couplers.
