Patent ID: 8659370

Claim:
An electronic apparatus comprising a first article, a second article and a high-frequency signal transmission line, the high-frequency signal transmission line comprising: an element assembly formed of one or more insulating layers, the element assembly having a first main surface and a second main surface; a linear signal line disposed in the element assembly; a first ground conductor that is disposed in the element assembly, faces the signal line at a first distance, and continuously extends along the signal line, the first ground conductor being located near the first main surface with respect to the signal line; and a second ground conductor that is disposed in the element assembly, faces the signal line at a second distance smaller than the first distance, and has a plurality of openings arranged along the signal line, the second ground conductor being located near the second main surface with respect to the signal line; wherein a main surface of the high-frequency signal transmission line that is located near the first ground conductor with respect to the signal line contacts with the first article; and wherein a main surface of the high-frequency signal transmission line that is located near the second ground conductor with respect to the signal line faces the second article at a specified distance.
