Signal transmission device having multilayer structure

Abstract

A signal transmission device includes a dielectric layer, a first signal layer, a second signal layer, and a set of signal lines. The dielectric layer is stacked between the first signal layer and the second signal layer. The set of signal lines, arranged in parallel along a predetermined direction, is configured to transmit a physical layer signal. The set of signal lines includes a first signal line, a second signal line, a third signal line and a fourth signal line. The first signal line is arranged in the first signal layer. The second signal line and the third signal line are arranged in the second signal layer. A distance from the fourth signal line to one of the first signal line and the third signal line is equal to a distance from the second signal line to the other of the first signal line and the third signal line.
