Automobile antenna system for diversity reception |
摘要 |
An automobile antenna system for diversity reception includes high-frequency pickups for effectively picking up the high-frequency surface currents which are induced on a vehicle body by broadcast waves and which flow concentratedly on the marginal edge portions of the vehicle body. The high-frequency pickups are disposed on both sides of the roof panel at the rear and front portions of a vehicle body in close proximity to the marginal edge and in a concealed state without any external exposure. The pickup that enjoys the optimum reception at any given time is selected from among the pickups by automatic changeover.
