A transmission apparatus (10) includes a communication device (30), comprising two input/output terminals (20a, 20b), and a terminal line (40) connected to the first input/output terminal (20a) and having an electrical length of substantially 90°. By the second input/output terminal (20b) electrically coupling with a transmission medium (50) comprising a conductor or a dielectric, a high frequency signal or electric power is transmitted to another transmission apparatus coupled electrically to the transmission medium (50). |
