1. A communication apparatus, comprising:
a coupler that is connected to a cable to which a first communication apparatus is connected, the first communication apparatus performing communication based on a wired communication scheme;
communication circuitry that is connected to the coupler;
an antenna that is connected to the coupler; and
power source circuitry, which, in operation, receives direct current power from the cable and supplies power to the communication circuitry,
wherein the antenna, in operation, radiates a signal of the wired communication scheme to a second communication apparatus, and receives a signal of the wired communication scheme from the second communication apparatus,
wherein the coupler, in operation:
outputs, to the cable and the antenna, the signal of the wired communication scheme outputted from the communication circuitry,
outputs, to the communication circuitry and the cable, the signal of the wired communication scheme received by the antenna, and
outputs, to the communication circuitry and the antenna, the signal of the wired communication scheme received from the cable, and
wherein the coupler comprises a capacitor that, in operation, prevents inflow of the direct current power to the communication circuitry and the antenna.
