VEHICLE ANTENNA SYSTEM USING STEERING HANDLE OR HANDLE COVER CAPABLE OF WIDENING BANDWIDTH

摘要

PURPOSE: A vehicle antenna system is provided to widen a bandwidth and achieve improved performance of an antenna by increasing the effective size of the antenna. CONSTITUTION: A vehicle antenna system comprises a conductive wire arranged in a steering wheel(6) or a handle cover of a vehicle so as to receive broadcast waves; a connection extension wire for connecting the conductive wire to an impedance matching unit(3); the impedance matching unit for converting impedances of both ends of the connection extension wire to specific impedances; a low noise amplifying unit(4) for amplifying the signal passed through the impedance matching unit and impedance matched; a power unit(9) for supplying power to the low noise amplifying unit; and a coaxial cable(8) for connecting the amplified signal passed through the low noise amplifying unit to a broadcast receiver.
