Abstract
A transmission apparatus includes a communication unit, including input/output terminals and two coupling electrodes. An input/output circuit of the communication unit is configured to function interchangeably. The two coupling electrodes are arranged along the longitudinal direction of the transmission medium, when coupled to the transmission medium. When the length from one coupling electrode of the two coupling electrodes to one end of the transmission medium in the longitudinal direction thereof is an electrical length in a range of (2n·90±45)° of the electrical signal and the length from another coupling electrode of the two coupling electrodes to another end of the transmission medium in the longitudinal direction thereof is an electrical length in a range of ((2n+1)·90±45)° of the electrical signal while the two coupling electrodes are coupled to the transmission medium, the communication unit transmits and receives the electrical signal to and from another transmission apparatus.
