Title:
TRANSMISSION LINE
Document Type and Number:
WIPO Patent Application WO/2018/135475
Kind Code:
A1
Abstract:
Provided is a transmission line which has a curved section and in which transmission loss is inhibited in a signal line disposed inside the curved section. This transmission line is provided with: a laminated insulation body obtained by laminating a plurality of insulating base material layers; a plurality of signal conductors which are disposed within the laminated insulation body so as to extend in a transmission direction along the insulating base material layers; and a plurality of ground conductors which sandwich, in the laminating direction, the respective signal conductors via the insulating base material layers. The transmission line has at least one curved section which is curved along a surface orthogonal to the laminating direction. The plurality of signal conductors are disposed so as to be separated from each other in the direction orthogonal to the transmission direction as viewed from the laminating direction. The plurality of signal conductors include a first signal conductor disposed inside the curved section and a second signal conductor disposed outside the curved section. Further, the distance between the ground conductors that sandwich the first signal conductor is narrower than the distance between the ground conductors that sandwich the second signal conductor.
