Abstract
Provided is an apparatus for tuning the voltage standing wave ratio (VSWR) of a base station system in a wireless communication network, the apparatus comprising: a VSWR changing unit for changing the characteristics of the VSWR of an antenna by changing electrical signal transmission characteristics of an internal power feedline by means of an external operation, or by changing the characteristics for transceiving a radiating member; a driving unit for driving the VSWR changing unit in accordance with a control signal; a VSWR detection unit for detecting the corresponding VSWR for the installed antenna and generating a detection signal on the basis thereof; and a control unit for controlling the actions of the VSWR changing unit for changing the VSWR characteristics by controlling the operation of the driving unit, if a VSWR characteristic is determined to be in an abnormal state on the basis of the detection signal generated by the VSWR detection unit.
