1. An antenna performance test system, comprising:
a first antenna disposed within a shield box in which a test target terminal is disposed and configured to receive a response signal output by the test target terminal;
a second antenna disposed to be spaced apart from the first antenna within the shield box and configured to receive the response signal output by the test target terminal; and
a tester configured to generate a UWB communication performance measurement value of the test target terminal based on first response signals for a first test signal, which are received from the first antenna and the second antenna, after outputting the first test signal that is a UWB band signal to the first antenna in response to an input of a first test mode setting signal and to generates a BLE communication performance measurement value of the test target terminal based on a second response signal for a second test signal, which is received from the first antenna, after outputting the second test signal that is a BLE band signal to the first antenna in response to an input of a second test mode setting signal.
