Abstract

A glass antenna device for an automobile capable of receiving well signals in a long wave broadcast band and an FM broadcast band wherein a series resonance is generated by a coil 31 disposed between an antenna conductor 3 and a receiver 7, a parallel resonance is generated by a choke coil 9 disposed between a defogger 90 and the automobile body as the earth, and a high frequency choking coil 52 for blocking an FM broadcast band signal is connected between the antenna conductor 3 and the defogger 90 to prevent the FM broadcast band signal exited in the antenna conductor 3 from leaking to the automobile body.
