Abstract: Disclosed are an apparatus for measuring radiated power and a method thereof. The apparatus for measuring radiated power includes: a measurement unit configured to receive an RF signal radiated from an antenna of the wireless communication device to generate a radiated power measurement value; a driving unit configured to vertically ascend or descend the measurement unit from the ground; and an operation control unit configured to control the driving unit to ascend the measurement unit to a point at which the antenna is installed and convert the radiated power measurement value into a measurement value on a target point. In accordance with the embodiment of the present invention, even when the antenna of the wireless communication device is inclined to the ground, the radiated power of the wireless communication device can be accurately measured by compensating for the change in the measurement distance due to the inclined angle.
