Abstract
The present invention provides a diversity type automobile antenna system comprising a pair of high-frequency pickups for mounted on the vehicle body at one or more locations whereat surface high-frequency currents will be induced by radio or other waves with higher densities, said high-freqnency pickups being arranged such that one of said high-frequency pickups can complement the other with respect to sensitivity. The above locations on the vehicle body include the marginal edge of a closure such as trunk lid, roof or engine hook, and various connections between each adjacent vehicle portion of flat configuration such as pillars supporting the roof panel or trunk hinges. One of the high-frequency pickups are adapted to be automatically selected such that it can receive radio or other waves more sensitively.
