ANTENNA SYSTEM OF MOBILE COMMUNICATION BASE STATION

摘要

The present invention is an antenna system of a mobile communication base station, comprising: a signal separation unit which is arranged within a radome of an antenna, and which separates a synthetic signal of a wireless signal transmitted from a main system of a base station through a feeder cable, a direct current power signal and a control signal having a preset format for controlling the antenna, in such a manner that the direct current power signal and the control signal are output by being separated from the wireless signal and the wireless signal is provided to an antenna unit; and equipment to be remotely controlled having a modem for receiving the direct current power signal and the control signal output from the signal separation unit and using the direct current power signal as an operating power and converting the control signal into a format which is preset to be internally recognizable in the radome of the antenna, the equipment to be remotely controlled performing an antenna control operation according to a control signal.
