GLASS ANTENNA SYSTEM FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a vehicle glass antenna system by which an excellent characteristic is obtained in a high frequency band and which is commonly used or coexists with an electric heating conductive film. SOLUTION: A planar and rectangular antenna conductor 2 is arranged on the adhesive surface or the in-vehicle surface of a planar glass windshield 1 which is formed of laminated glass and a power feeding point 3 and a ground point 4 are arranged on the antenna conductor 2 or in the neighborhood of it. The power feeding point 3 is connected to an amplifier 8 which constitues an exciting part via a conducting wire and also the amplifier 8 is connected to communication equipment 9 consisting of a receiver or a transceiver. The ground point 4 is connected to the grounding wire of a vehicle via the conducting wire. The antenna conductor 2 is constituted of a transparent conductive film, etc., which is commonly used for or coexists with the electric heating conductive film.
