HIGH-FREQUENCY SIGNAL LINE

摘要

The purpose of the present invention is to provide a high-frequency signal line that minimizes low-frequency noise and can be reduced in thickness. A dielectric sheet (18) has a top surface and a bottom surface. A signal line (20) is provided on the top surface of the dielectric sheet (18). A ground conductor (22) is provided, along the signal line (20), on the top surface of the dielectric sheet (18). A plurality of high-dielectric-constant sections (32) that each have a higher relative dielectric constant than the dielectric sheet (18) are lined up along the signal line (20) and are in contact both with parts of the signal line (20) and with parts of the ground conductor (22).
