Communication device
A communication device includes a main circuit board, a cable, and an active antenna device. The cable is configured to deliver both a DC (Direct Current) control signal and an RF (Radio Frequency) signal. The active antenna device includes a comparator, a transmission path, a reception path, and an antenna element. The comparator recovers the DC control signal. The antenna element selects the transmission path or the reception path according to the recovered DC control signal, so as to transmit or receive the RF signal.
