Abstract

A glass antenna device for a vehicle includes an FM antenna (as a receiving antenna for short-waves) and a defogger provided on a rear window glass of the vehicle, and an AM antenna (as a receiving antenna for medium-waves) provided on a side window glass fixed at a different position from the rear window glass of the vehicle. Since the AM antenna is spaced relatively far distant from electric equipments such as a rear wiper, stop lamps and indicators disposed at a rear portion of the vehicle, noises generated from the electric equipments are unlikely to be mixed in a transmission line of the antenna device.
