Title:
SIGNAL LINE AND CIRCUIT BOARD
Document Type and Number:
WIPO Patent Application WO/2010/131523
Kind Code:
A1
Abstract:
Provided is a signal line which can be easily bent to a U-shape and suppress unnecessary radiation. A circuit board is also provided. In a line part (16), a plurality of line part sheets (31) composed of a flexible material are laminated. Signal lines (42c, 43c, 44c) extend in the x axis direction in the line part (16). In the line part (16), ground lines (32b, 33b, 34b) are provided further towards the positive side in the z axis direction than the signal lines (42c, 43c, 44c) and have a line width equal to or smaller than that of the signal lines (42c, 43c, 44c). The ground lines (32d, 33d, 34d) are provided further towards the negative side in the z axis direction than the signal lines (42c, 43c, 44c) in the line part (16). The signal lines (42c, 43c, 44c) overlap the ground lines (32b, 33b, 34b, 32d, 33d, 34d) in planar view from the z axis direction.
