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).
