Abstract
This specification discloses an excellent communication device of a field coupling type that increases field coupling efficiency between electrodes and realizes a small-sized device. This specification also discloses a communication system and an electrode. A communication deviceincludes: a first resonant circuitconnected in series to an electrode unitformed with two conductor plates; and a second resonant circuitconnected in parallel to the electrode unitand the first resonant circuit, which are connected in series. The constant of a resonant circuit is determined so that the voltage Vto be applied to the electrode unitbecomes higher than the voltage Vto be applied to the electrode unitand the first resonant circuitconnected in series. In this manner, a field coupling electrode that has a very high coupling strength at a target frequency is obtained.
