COMMUNICATION DEVICE

摘要

PURPOSE: A communication device is provided to transmit a signal to an antenna among a plurality of antennas corresponding to the frequency of the signal. CONSTITUTION: A light source(110) outputs an optical signal including a target frequency component corresponding to target frequency. A plurality of antennas(120) comprises different frequency characteristics. A control circuit(130) transfers the optical signal to an antenna selected among plurality of antenna corresponding to a target frequency component having frequency characteristic. The selected antenna receives input of the optical signal. The selected antenna transmits the transmission signal having goal frequency component.
