ABSTRACT:
A differential transmission line includes: a substrate; a ground conductor layer; and a first and a second signal conductor disposed in parallel to each other on the substrate. The first signal conductor and the ground conductor layer compose a first transmission line, whereas the second signal conductor and the ground conductor layer compose a second transmission line. The first transmission line and the second transmission line compose a differential transmission line. The differential transmission line includes a curved region, with a straight region being connected to each end of the curved region. In the ground conductor layer in the curved region, a plurality of slots orthogonal to a local transmission direction of signals in the curved region are formed, and the slots are connected to one another on the inner side of the curvature.
