Disclosed is a communications signal amplifying device for a vehicle, which can amplify communications signal strength of a communications device (e.g., GPS navigation terminal, hi-pass terminal, RFID card, etc.) installed in a vehicle. According to an embodiment of the present invention, the communications signal amplifying device comprises: a transmitting/receiving module for transmitting and receiving a communications signal with a film antenna provided in the vehicle and the GPS navigation terminal, the hi-pass terminal, and the RFID card, provided in the vehicle; a multi-combiner for receiving a communications signal for the GPS navigation terminal, a communications signal for the hi-pass terminal, and a communications signal for the RFID card from the transmitting/receiving module, and integrating the received communications signals into a single signal so as to transmit the integrated single signal to the film antenna, or individually branching the communications signal for the GPS navigation terminal, the communications signal for the hi-pass terminal, and the communications signal for the RFID card, which are integrated and received through the film antenna, so as to transmit the branched signals to the transmitting/receiving module; and an amplifier for amplifying a communications signal which is transmitted and received between the transmitting/receiving module and the multi-combiner by a predetermined strength. |
