| 摘要 | Unwanted radiation is reduced in a high-frequency signal transmission line that includes a ground conductor provided with an opening that overlaps a signal line. A dielectric element assembly has a relative dielectric constant ∈1 and has a first principal surface and a second principal surface. A signal line is provided in the dielectric element assembly. A ground conductor is provided in the dielectric element assembly and on the first principal surface side with respect to the signal line, faces the signal line, and is provided with an opening that overlaps the signal line. A high dielectric constant layer has a relative dielectric constant ∈2 higher than the relative dielectric constant ∈1 and is provided on the first principal surface so as to overlap the opening. | ||

| 主权项 | 1. A high-frequency signal transmission line comprising: an element assembly having a first relative dielectric constant and having a first principal surface and a second principal surface; a line-shaped signal line provided within the element assembly; a first ground conductor provided on the first principal surface side with respect to the signal line and facing the signal line, the first ground conductor being provided with a first opening that overlaps the signal line; and a first high dielectric constant layer having a second relative dielectric constant higher than the first relative dielectric constant and provided on the first principal surface so as to overlap the first opening. | ||
