Abstract: A positioning system executes wireless communication with a portable terminal by adopting a radio wave of 1 GHz or higher to determine a position of the portable terminal relative to a vehicle. The positioning system includes a vehicle exterior communication device and a positioning device. The positioning device determines whether the portable terminal exists at an exterior operating area being a region outside a vehicle compartment within a predetermined operating distance from the vehicle, based on a reception status of the wireless signal received by the vehicle exterior communication device from the portable terminal in a first mode of the vehicle exterior communication device, and determines whether the portable terminal exists inside the vehicle compartment, based on the reception status of the wireless signal received by the vehicle exterior communication device from the portable terminal in a second mode of the vehicle exterior communication device.

Abstract: The present disclosure relates to an antenna return loss compensation apparatus and method of a radar and a radar apparatus using the same. The antenna return loss compensation apparatus may include a compensation information calculator configured to calculate return loss compensation information for compensating for a frequency-band based antenna return loss, and a return loss compensator configured to apply return loss compensation information to a reception signal that is reflected from an object and is received, so as to generate a final reception signal, may calculate and store, in advance, compensation information for a return loss occurring in the antenna, may perform compensation associated with the magnitude of a reception signal when measurement is performed using the radar, so that the reception signal has the same magnitude, whereby a radar's performance deterioration attributable to the return loss of the antenna may be minimized.

Abstract: A portable radio communication device D′ with adjustable total gain and an associated gain adjustment method via a conductive metal frame C situated at the periphery of the portable device D′. For this purpose, the frame C includes several metal sections P1, P2, P3, P4 not connected to each other and separated from each other by openings F1, F2, F3, F4. Switching elements S1, S2, S3, S4 make it possible to electrically connect two consecutive sections in such a way as to modify the length of the sections and to modify the electromagnetic coupling between the antenna A and the metal frame C. The modification of coupling causes a modification of the value of the resultant gain Gr of the antenna A. A calibration step makes it possible to select the sections to be connected together in order to obtain the desired resultant gain Gr of the antenna A.
