High-frequency signal transmission line and electronic device

摘要

A high-frequency signal transmission line includes a plate-shaped dielectric element assembly, a linear signal line, and a first ground conductor. The linear signal line is provided at the dielectric element assembly and includes a plurality of thick portions and a plurality of thin portions with a smaller width than the thick portions. The first ground conductor is provided at the dielectric element assembly and positioned on one side in a normal direction to the dielectric element assembly relative to the signal line. The first ground conductor includes a plurality of openings overlapping with the signal line and also includes bridge portions provided between the openings so as to cross the thin portions. The bridge portions cross the thin portion obliquely when viewed in a plan view in the normal direction to the dielectric element assembly.
