GLASS ANTENNA DEVICE FOR VEHICLE AND RADIO RECEIVER APPARATUS USING THE SAME

摘要

The present invention provides a vehicle glass antenna device which can receive AM and FM waves with high sensitivity without a choke coil and thus facilitates basic designing and adjustment of its antenna patterns. The glass antenna device includes an AM antenna provided so as not to be capacitively coupled with a defogging heater unit also installed on a vehicle window glass. An FM antenna in the form of a single horizontal antenna conductor element is disposed on the window glass between the defogging heater unit and the AM antenna. The glass antenna device further includes an AM amplifier for amplifying a signal received via the AM antenna and an FM amplifier for amplifying a signal received via the FM antenna.
