APPARATUS FOR USING COMMON ANTENNA FEEDER IN A BASE TRANSCEIVER SYSTEM

摘要

An apparatus for sharing an antenna feeding line of a base station is provided to reduce a construction cost by reducing an installation quantity of feeding line. An apparatus for sharing an antenna feeding line of a base station includes a base station device(10), transmission and reception units(11-13), antennas(21-23), a first frequency transformer(100), and a second frequency transformer(200). The base station device transmits and receives a signal of the same frequency band through a plurality of transmission and reception units(11-13). A base station has the plurality of antennas(21-23) which are connected to correspond to the transmission and reception units(11-13) through a feeding line. The antenna feeding line sharing apparatus uses a common feeding line from each of transmission and reception units(11-13) to the antennas(21-23). A first frequency transformer(100) transforms a signal of a plurality of transmission and reception units to a signal of a different frequency band, and transmits the transformed signal to the antennas through one common feeding line. The second frequency transformer(200) divides the signal received through the common feeding line into frequency bands. The second frequency transformer(200) reproduces a signal having an original frequency band, and outputs the reproduced signal to the antennas(21-23).
