1. A wireless communication apparatus comprising:
a communication coupler including a plurality of substrates including a first substrate and a second substrate, and a connection signal line; and
a circuit configured to transmit or receive a signal to or from the communication coupler,
wherein the first substrate and the second substrate are opposed to each other in a longitudinal direction of the communication coupler,
wherein the first substrate includes a first signal line, a second signal line, a third signal line, a distributor, and a terminating resistor,
wherein at the distributor, the first signal line branches into the second signal line and the third signal line,
wherein the second signal line is terminated at the terminating resistor at an end of the first substrate,
wherein the second substrate includes a fourth signal line,
wherein the connection signal line connects the third signal line and the fourth signal line, and
wherein a facing portion of the second signal line and a facing portion of the fourth signal line are opposed to each other, and at least one of the third signal line or the connection signal line is configured such that a phase of a signal at the facing portion of the second signal line and a phase of a signal at the facing portion of the fourth signal line are continuous.
