Disclosed is an antenna performance test system for testing the performance of UWB and BLE antennas by reflecting a loss of a cable without changing test conditions. The disclosed antenna performance test system comprises a tester, which: responds to a first test mode setting signal so as to output, to a first antenna, a first test signal (a UWB band signal), and then generate a UWB communication performance measurement value based on a first response signal received from the first antenna and a second antenna with respect to the first test signal; and responds to a second test mode setting signal so as to output, to the first antenna, a second test signal(a BLE band signal), and then generate a BLE communication performance measurement value based on a second response signal received from the first antenna with respect to the second test signal.

UWB antenna and BLE antenna performance test system

Disclosed is a smart tracker for communicating with a parent terminal by Bluetooth communication and communicating with the parent terminal by ultra-wideband communication during positioning. The disclosed smart tracker comprises: a first housing; a second housing coupled to the first housing to form an inner space; a circuit board arranged in the inner space formed by the first housing and the second housing; a buzzer mounted on the lower surface of the circuit board; a battery mounted on a surface of the circuit board; a first antenna arranged on the upper surface of the circuit board and spaced from the areas on which the buzzer and the battery are mounted; and a second antenna arranged on the upper surface of the circuit board and spaced from the areas on which the buzzer and the battery are mounted and from the first antenna.
