ABSTRACT:
A broadband FM antenna is suitable for mounting on an inner surface of a rear window glass of a motor vehicle above an electric rear window defogger grid also mounted on the glass and made of the same frit material. The antenna has an extended range of reception across a commercial FM band without the need for an antenna boost amplifier and is capable of use in multiple countries having different commercial FM bands. The antenna comprises a plurality of horizontal frit lines extending outward from a series of points near the horizontal center of the rear window as described and claimed herein. Some of these horizontal elements are joined by outer connecting frit lines at their outer ends and all are connected at their inner ends by a plurality of inner connecting elements connecting all of the points together. The frit lines essentially form a pair of horizontal antenna elements, each tuned to one quarter of a different commercial FM band wavelength so that the antenna spans the desired band or bands. A connecting pad of frit material on the window glass connected to two of the points provides an antenna connection.
