A communication apparatus that communicates with another communication apparatus through electromagnetic field coupling, the communication apparatus comprising:
- a first conductor configured to transmit or receive a signal through the electromagnetic field coupling;
- a metal member configured to function as a ground of the first conductor;
- a second conductor connected to the first conductor;
- an extraction electrode;
- and
- a circuit, the circuit being a transmission circuit or a reception circuit;
- wherein the first conductor has one side connected to the second conductor and another side connected to the circuit being the transmission circuit or the reception circuit,
- wherein a first surface of the extraction electrode is connected to the second conductor, and
- wherein a second surface of the extraction electrode is terminated to the metal member via a termination resistor.
A wireless communication system comprising:
- a transmission or reception apparatus that includes:
- a first conductor;
- a metal member configured to function as a ground of the first conductor;
- a second conductor connected to the first conductor;
- an extraction electrode connected to the second conductor and terminated to the metal member;
- and
- a circuit, the circuit being a transmission circuit or a reception circuit,
- wherein the first conductor has one side connected to the second conductor and another side connected to the circuit being the transmission circuit or the reception circuit, and
- another transmission or reception apparatus that includes another conductor spaced from the first conductor and electromagnetically coupled to the first conductor.
