Abstract
Abstract In the vehicle antenna, a GPS antenna, a radio wave beacon antenna for VICS/automatic rate, and an optical beacon antenna are incorporated into between the mirror of a room mirror and a cover and they are united together into an integrated body. The vehicle antenna is structured such that it is allowed to transmit and receive signals with respect to a GPS, a VICS/automatic rate beacon, and an optical beacon through the windshield of a vehicle. This structure eliminates the need to install the respective antennas of the vehicle antenna onto a vehicle body and an instrumental panel, thereby being able to improve the appearance of the interior of the vehicle. Also, since the vehicle antenna is incorporated in the room mirror, the vehicle antenna is not visible directly to the eyes of a driver and is kept from reflecting its shade into the windshield to thereby prevent interference with the driving operation of the driver.
