Abstract

The present invention provides a diversity reception type automotive antenna system comprising a pole type antenna as a main antenna and a high-frequency pickup device as a sub-antenna. The high-frequency pickup is mounted on a connection between adjacent vehicle portions and functions to detect surface high-frequency currents induced on the vehicle body by radio or other waves which flow on the connection. The high-frequency pickup can readily be installed on the vehicle body without any externally projecting portion which would otherwise damage the aesthetic design of the vehicle body.
