The invention relates to an antenna on a vehicle rear window glass for the reception of FM radio broadcasting and TV broadcasting in both the VHF and UHF bands. The window glass is provided with defogging heater strips, and the antenna uses a space left above the heater strips. The antenna is constructed of a plurality of linear elements comprising (A) a combination of two primary elements, which are spaced from each other in the direction widthwise of the window glass and each of which makes the perimeter of a horizontally elongate rectangle or two horizontal sides and one vertical side of the rectangle, and a connection line which connects the two primary elements to each other and (B) a secondary element having a first part which extends from one of the two primary elements or the connection line to a point between the combination (A) and the upper edge of the window glass and a second part which extends horizontally from said point toward a side edge of the window glass and is connected to a feed point located near the side edge of the window glass. Optionally a supplementary element or supplementary elements may be connected to the combination (A) and/or the secondary element (B).
