Abstract
A glass antenna system for vehicles to receive AM and FM bands is provided. An electrically conductive transparent film is formed on a side glass. A silver printed line have a wide width is formed around the electrically conductive transparent film. A loop-shaped silver printed line is provide surrounding the film, which is capacitively coupled to the body. In this manner, an opening is formed in a space between the silver printed line and the electrically conductive film. An electrically shorted portion is provided between the silver printed line and the electrically conductive film. A coaxial feeder for AM/FM is provided. A central conductor of the feeder is connected to the silver printed line and the outer conductor to the body.
