Abstract: In a system for testing antenna performance, antenna performance is tested by reflecting the loss of a cable used in the antenna performance test. The system for testing antenna performance includes a tester having a test port, the test port being connected, via a cable, to an antenna that communicates with a terminal to be tested, in a shield box, when a test mode is set, wherein the tester outputs a test signal to the test port, receives a response signal corresponding to the test signal via the test port, and obtains a value, as a communication performance measurement value, by adding a calibration value to a reception signal strength of the response signal.

Abstract: Provided is a positive temperature coefficient (PTC) unit for a vehicle heater. The PTC unit according to an exemplary embodiment of the present invention includes: a heat generation part which includes PTC elements; and a heat radiation part which is provided on at least one surface of the heat generation part and includes a heat radiation base material and a heat radiation film provided on at least a portion of an outer surface of the heat radiation base material to improve heat radiation performance. According to the present invention, improved heat radiation performance may be exhibited, and concurrently, heat radiation performance due to excellent durability may be exhibited for a long period of time without a structural change for increasing a specific surface area of a heat radiation part while reducing an air ventilation property, so as to improve heat radiation performance. In addition, since an air ventilation property of the heat radiation part is increased, it is possible to prevent increases in noise and power consumption due to excessive use of peripheral devices such as a fan. Furthermore, since it is possible to prevent overheating of a PTC module and overload of a PTC module control circuit, which are caused by a reduction in the air ventilation property of the heat radiation part, a high-priced and high performance control circuit may not be required, thereby implementing a PTC heater for a vehicle with reduced production costs.
