PURPOSE: Powerless wireless signal analysis system and a method thereof are provided to increase utilization of a sensor by obtaining more accurate information by accurately analyzing a signal of a sensor. CONSTITUTION: A signal generator(100) transmits a vector signal for signal analysis. Also, the signal generator transmits the vector signal for signal analysis to a powerless wireless sensor(200) through the first antenna using a divider(110) having a first antenna and a second antenna, and transmits a signal analysis apparatus(300) through the second antenna. The powerless wireless sensor transmits a return signal corresponding to the vector signal by receiving a vector signal generated in the signal generator and includes a circulator(220) having the first antenna and the second antenna. A first port of the circulator is connected to the first antenna receiving a vector signal and a second port of the circulator is connected to the signal generator generating a return signal corresponding to the vector signal and a third port of the circulator is connected to the second antenna generating a return signal.
