Abstract: A wire harness includes a flat shielded cable, a first device connected to one end of the flat shielded cable, and a second device connected to the other end of the flat shielded cable. The flat shielded cable includes a plurality of conductors arranged in parallel, an insulating jacket section that covers the plurality of conductors and has an exposed conductor section which exposes a part of at least one of the conductors, and a shielding member that covers an outer periphery of the jacket section. A signal is transmitted from the first device to the second device through a conductor other than the conductor provided with the exposed conductor section. The at least one of the conductors is connected to a ground at a position between the exposed conductor section and the second device.

Abstract: A transmission line includes first and second conductor patterns that serve as signal transmission paths, first and second insulating layers that hold the first and second conductor patterns therebetween, and a third conductor pattern that is arranged between the first and second conductor patterns. No signal is transmitted through the third conductor pattern. A relation 0.5 w?S1?1.5 w and a relation 0.5 w?S2?1.5 w are satisfied in a range of a relation S?2 w, wherein S expresses a distance between the first conductor pattern and the second conductor pattern, w expresses a width of each of the first conductor pattern and the second conductor pattern, S1 expresses a distance between the first conductor pattern and the third conductor pattern, and S2 expresses a distance between the second conductor pattern and the third conductor pattern.

Abstract: A structure for arranging in a vehicle a planar antenna unit including a planar antenna provided in a roof of a vehicle is provided. The planar antenna unit includes: a planar antenna including an antenna which receives a radio wave from an outside and an amplifier which amplifies the radio wave received by the antenna; and a long line which outputs a radio wave signal amplified by the amplifier. The planar antenna and the line are formed into a sheet-like structure. The line is disposed within a pillar of the vehicle such that a leading end portion of the line extends to a position beyond a lower end of the pillar.
