Title:
TRANSMISSION LINE
Document Type and Number:
Japanese Patent JP2014011528
Kind Code:
A
Abstract:

To provide a transmission line having flexibility and stability of characteristic impedance.

A transmission line 1 includes ground conductor patterns 11-15, a signal line conductor 21, and base material layers 31-34. The signal line conductor 21 is formed between the ground conductor pattern 11 and the ground conductor pattern 15. The ground conductor pattern 13 is formed to surround the signal line conductor 21, when viewed from a direction perpendicular to a principal surface of the ground conductor pattern 11, and to overlap the signal line conductor 21, when viewed from a direction in parallel with the principal surface. The ground conductor patterns 12, 14 are formed to surround the signal line conductor 21, when viewed from a direction perpendicular to the principal surface, and to be spaced from the ground conductor pattern 13, when viewed from a direction in parallel with the principal surface. The base material layers 31-34 are formed so as to fill between the ground conductor pattern 11 and the ground conductor pattern 15.
