Keating & Bennett, LLP
High-frequency signal transmission line, electronic device and manufacturing method of high-frequency signal transmission line
A high-frequency signal transmission line includes a dielectric body including dielectric layers stacked together, a linear signal line provided in the dielectric body, a first ground conductor provided at the dielectric body, at a first side of the signal line in a stacking direction so as to face the signal line, and a subsidiary member provided at the dielectric body, at a second side of the signal line in the stacking direction so as to face a central portion of the signal line in a line-width direction. In a sectional view along a plane perpendicular or substantially perpendicular to an extending direction of the signal line, the signal line is curved such that side portions of the signal line in the line-width direction are farther away from the first ground conductor than a central portion of the signal line in the line-width direction.
