Title:
DIVERSITY ANTENNA FOR DIVERSITY ANTENNA DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP3803536
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To attain the improvement of receiving performance, the reduction of costs, and the simplification of wiring without using any amplifier in a diversity antenna arranged on the rear window glass of a vehicle.
SOLUTION: A low resistance connecting conductor 12 whose minimum length is about λ/10 is arranged at each edge part of a conductive part 1 formed on a glass, an antenna connecting point 5 is formed at one side of a pair of terminals of the low resistance connecting conductor 12, and an impedance connecting part 8 is formed at the other terminal. Also, a connected network 4 is connected to the antenna connecting part 5, and an electronic controllable impedance network 6 is connected to the impedance connecting part 8. Thus, the impedance value of the impedance network 6 is adjusted, so that an output can be extracted from the connected network 6.
