GLASS ANTENNA SYSTEM FOR AUTOMOBILE

摘要

PROBLEM TO BE SOLVED: To provide a glass antenna system for automobile that has satisfactory antistatic electricity characteristic and can excellently receive both AM and FM bands. SOLUTION: A coil 31 between a defogger 90 and a receiver 7 causes a series resonance and a coil 32 between the defogger 90 and a car body grounding point causes a parallel resonance in this glass antenna system. A high frequency choke coil 52 for interrupting FM signals is connected between an antenna conductor 3 and the defogger 90, and surge voltage absorbing elements 80, 81 are connected between a signal line and the car body grounding point.
