To increase a communication area without changing an existing communication system.SOLUTION: A vehicle communication system includes: parallel wiring 60; a plurality of LCR antennas 11-14; and on-vehicle machine. The parallel wiring 60 includes: first wiring 61 and second wiring 62 which are connected in parallel to each other. Each of the plurality of LCR antennas 11-14 includes: a coil 51; a capacitor 52; and a resistor 53, and is arranged at each of the first wiring 61 and the second wiring 62, thereby impedance being equal to each other. The on-vehicle machine includes an output port 34 in which a first terminal (namely, a first connection point CP1) of the parallel wiring 60 and a second terminal (namely, a second connection point CP2) of the parallel wiring 60 are connected, and controls the plurality of LCR antennas 11-14.SELECTED DRAWING: Figure 2 【課題】既存の通信システムを変更することなく通信エリアを拡大する。【解決手段】車両用通信システムは、並列配線６０と、複数のＬＣＲアンテナ１１～１４と、車載機とを備える。並列配線６０は、互いに並列に接続される第１配線６１と第２配線６２とを備える。複数のＬＣＲアンテナ１１～１４は、コイル５１とコンデンサ５２と抵抗器５３とを備え、第１配線６１および第２配線６２のそれぞれに配置され、互いにインピーダンスが等しい。車載機は、並列配線６０の第１端（すなわち、第１接続点ＣＰ１）と並列配線６０の第２端（すなわち、第２接続点ＣＰ２）とが接続される出力ポート３４を備え、複数のＬＣＲアンテナ１１～１４を制御する。【選択図】図２
