Abstract

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 as a sub-antenna, the high-frequency pickup being mounted on a connection between each adjacent vehicle portions and functioning to detect surface high-frequency currents induced on the vehicle body by radio or other waves and flowing 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 design of the vehicle body.

Claim 1
Independent Claim 77 words
An automotive antenna system comprising a pole type antenna mounted on the vehicle body at a location and a high-frequency pickup mounted on the vehicle body at a connection between each adjacent vehicle portions and spaced from said location, said high-frequency pickup functioning to detect surface high-frequency currents induced on the vehicle body by radio or other waves and flowing on said connection, said pole antenna and high-frequency pickup defining a space diversity reception type antenna unit.
Claim 2
Dependent Claim 77 words
An automotive antenna system comprising a pole type antenna mounted on the vehicle body at a location and a high-frequency pickup mounted on the vehicle body at a connection between each adjacent vehicle portions and spaced from said location, said high-frequency pickup functioning to detect surface high-frequency currents induced on the vehicle body by radio or other waves and flowing on said connection, said pole antenna and high-frequency pickup defining a space diversity reception type antenna unit.
Claim 3
Dependent Claim 48 words
An automotive antenna system as defined in claim 1 wherein said pole antenna is mounted on the rearward portion of the vehicle body and wherein said high-frequency pickup is mounted on one of the front pillars of the vehicle body at the side opposite to said pole antenna.
Claim 4
Dependent Claim 63 words
An automotive antenna system as defined in claim 2 wherein said high-frequency pickup includes a casing of electrically conductive material and a loop antenna disposed within said casing, said casing having an opening formed therein through which a portion of said loop antenna is externally exposed, the exposed portion of said loop antenna being located in close proximity to said one front pillar.
Claim 5
Dependent Claim 44 words
4 . An automotive antenna system as defined in claim 1 wherein said pole antenna is mounted on one of the front pillars of the vehicle body and wherein said high-frequency pickup is mounted on one of the trunk hinges of the vehicle body.
Claim 6
Dependent Claim 59 words
