ABSTRACT:
The invention provides an antenna disclosed on or in a vehicle window glass, e.g. an automobile rear window glass, for receiving FM broadcast waves. The antenna has a main element, which extends horizontally from a side marginal region of the glass pane to a middle region but does not intersect the longitudinal center axis of the glass pane, and a phase adjusting element which extends parallel to the main element from the same side marginal region and is connected at its end in the side marginal region to the main element by a perpendicular line. The feed point is connected to an arbitrary point on the perpendicular line. The main element may be folded so as to have at least one horizontally extending turn-back part. The phase adjusting element may extend to the opposite side marginal area of the glass pane and may be folded so as to have a turn-back part which extends horizontally without intersecting the center axis of the glass pane. This antenna is almost non- directional and is high in gain over the entire range of the 76-90 MHz band and the 88-108 MHz band.
