Abstract
Official abstract text for this publication.
A signal line and a circuit board that can be easily bent in a U shape and prevent unwanted emission include a line portion includes a plurality of laminated line portion sheets made of a flexible material. Signal lines extend within the line portion in an x-axis direction. Ground lines are provided within the line portion on a positive direction side in a z-axis direction with respect to the signal lines and have line widths equal to or smaller than the line widths of the signal lines. Ground lines are provided within the line portion on a negative direction side in the z-axis direction with respect to the signal lines. The signal lines overlap the ground lines when seen in a planar view from the z-axis direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A signal transmission line comprising: a line portion including stacked insulating sheets made of a flexible material such that the line portion can be bent; a signal line extending within the line portion; a first conductive layer provided within the line portion on one side in a lamination direction with respect to the signal line and having a line width equal to or smaller than a line width of the signal line; and a second conductive layer provided…
