COMMUNICATION SYSTEM, INTERFACE DEVICE, AND SIGNAL TRANSFERRING DEVICE

摘要

A communication system comprises a signal carrying apparatus having a first conductor portion (111) of which external shape is sheet-like and which serves as a conductor and a second conductor portion (121), the first and second electrodes being disposed substantially in parallel with each other, and an interface device having a first electrode (1211) and a second electrode (1222) opposed to the first conductor portion (111) for transmitting the electromagnetic field, and a normalized reactance derived from the reactance component of a sheet impedance in the signal transmitter is not extremely smaller than 1, and the normalized distance derived from a distance between the signal transmitter and the interface device made closer to substantially equal to 1 or less in the leak region (141) between the signal transmitter and the interface device and in the interval region (131) between the external shape of the first conductor portion (111) and the external shape of the second conductor portion (121).
