Differential mode transmission lines with weak coupling structure

摘要

A differential mode transmission line with a weak coupling structure is presented. The differential mode transmission line with a weak coupling structure includes a first transmission line and a second transmission line. The first transmission line includes a first wiring portion, a second wiring portion, and a third wiring portion. The second transmission line also includes a first wiring portion, a second wiring portion, and a third wiring portion. The wiring portions of the present disclosure are connected through connection portions, and the connection portions are designed as a corner structure. Due to the characteristics of the corner structure of the present disclosure, a pitch between the second wiring portions is greater than that between the first wiring portions or the third wiring portions, thereby generating a weak coupling structure to suppress common mode noises.
