ANTENNA DEVICE FOR AUTOMOTIVE VEHICLE

摘要

PURPOSE: A vehicular mirror have within an antenna apparatus is provided to prevent a deformation of an antenna according to the air resistance by mounting the antenna and accompanied circuit in the side view mirror and the rear view mirror. CONSTITUTION: The first coil(L1) is arranged in the cross direction in a mirror of vehicle to receive an electromagnetic waves. The first capacitor(C1) and the second capacitor(C2) are electrically connected in parallel to the first coil(L1). The second coil(L2) and the fourth coil(L4) is connected in parallel to the first coil(L1). The second coil(L2) is connected in parallel to the first coil(L1), and the fourth coil(L4) is connected in parallel to the first coil(L1). The third coil(L3) is connected to between the first coil(L1) and the ground. The third coil(L3) is longitudinally connected to the lower end of the first coil(L1). The first through forth coil(L1¯L4), the first capacitor(C1) and the second capacitor(C2) are installed at the printed circuit boards(P).
