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.

Disclosed is a flexible PCB RF cable having a ground pattern that is divided into two ground patterns, which are connected through a connection pattern arranged in an area overlapped with a signal line pattern, and thus cracks are minimized during bending. The disclosed flexible PCB RF cable comprises: a signal line pattern interposed between a first dielectric sheet and a second dielectric sheet; first and second lower ground patterns, which are mesh patterns arranged to be spaced from each other below the first dielectric sheet; a lower connection pattern connected to the first and second lower ground patterns; first and second upper ground patterns, which are mesh patterns arranged to be spaced from each other above the second dielectric sheet; and an upper connection pattern connected to the first and second ground patterns.

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.

Presented is a position-measuring device using UWB antenna, the position-measuring device distinguishing measurement targets positioned indoors from measurement targets positioned outdoors on the basis of UWB signals received from a plurality of UWB antennas. The presented position-measuring device includes: a first UWB antenna; a second UWB antenna; a third UWB antenna; a signal processing module which outputs a signal received from the first UWB antenna and a UWB signal received from at least one among the second UWB antenna and the third UWB antenna; and a position-measuring module which measures the position of the measurement target on the basis of the UWB signals output from the signal processing module.
