COMMUNICATION SYSTEM, INTERFACE DEVICE, AND SIGNAL CARRYING APPARATUS

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), and an interface device having a first electrode (1211) and a second electrode (1222) located near the first conductor portion (111), the normalized reactance derived from the reactance component of the sheet impedance in the signal carrying apparatus is not extremely smaller than 1, and the normalized distance derived from a distance between the signal carrying apparatus and the interface device made closer to substantially equal to 1 or less for transmitting the electromagnetic field in the leak region (141) between the signal carrying apparatus 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).
