Abstract
The present invention presents an antenna device for an automotive vehicle wherein a first coil is installed horizontally to receive radio signals. Capacitors are connected electrically and in parallel with the first coil. A second coil is connected electrically with the first coil and installed horizontally under the first coil. A third coil is connected electrically between the first coil and the ground and installed horizontally under the first coil. Additionally, a fourth coil is connected electrically between the first coil and the second coil and installed vertically under the first coil. This antenna device, now including the first to the fourth coils and capacitors, is installed in a mirror case for the car.
