Abstract
(EN)
This in-vehicle transmission system, which is mounted in a vehicle provided with one or a plurality of antennas and a plurality of in-vehicle machines, is provided with: a path unit through which a wireless signal, which has been received from an antenna side, is transmitted to an in-vehicle machine side; an in-vehicle machine side circuit unit which includes a plurality of wireless circuits that receive wireless signals of different frequency bands; and a power supply circuit which supplies power from the in-vehicle machine side to an antenna-side circuit through the path unit, wherein the plurality of wireless circuits are serially connected through a transmission line through which the wireless signals are transmitted, the plurality of wireless circuits are respectively connected to the plurality of in-vehicle machines through transmission lines through which the wireless signals are transmitted, the in-vehicle machine side circuit unit branches the wireless signals received from the path unit to impart the branched wireless signals to the respective wireless circuits, and the power supply circuit superimposes power on the transmission line at an opposite side part of the path unit with respect to the closest wireless circuit to the path unit in the transmission line.
