PURPOSE: A device for testing a VSWR(Voltage Standing Wave Ratio) of a receiving antenna in a W-CDMA mobile communication system is provided to oscillate a test signal for testing the VSWR with center frequencies and frequencies between the center frequencies, thereby testing the VSWR without influencing on a substantial communication service. CONSTITUTION: When a test request is sensed to test a VSWR, a controller determines oscillating frequency information and power level information of a test signal for testing the VSWR, and generates a test signal generation request including the determined oscillating frequency information and the power level information. A test signal generator(311) generates the test signal corresponding to the oscillating frequency information and the power level information, and transmits the test signal to an antenna(360). A VSWR detector(313) receives the test signal with a reflecting signal for the test signal from the antenna(360), and calculates the VSWR with the test signal and the reflecting signal. |
