  • Antenna device for vehicles
    Patent number: 6078294
    Abstract: A TV antenna assembly is constituted by a first belt-like antenna element and a second linear antenna element, and is stuck in a loop onto the inner surface of a door mirror case. Improved characteristics are obtained owing to a combination of the capacitance feature of the first antenna element and the inductance feature of the second antenna element. The wiring is easily routed since the antenna assembly is connected to the side of the car body through the second antenna element. The GPS antenna assembly is arranged on the rear side of the mirror.
