Abstract
A vehicle window glass is provided with an antenna to be fit in a window frame of a vehicle such as an automobile. The antenna comprises a plurality of antenna elements which are disposed on a portion of the glass extending generally alongside the window frame. Thus, the antenna elements are spaced from the window frame at a reference or ground potential and preferably close to the sides of the frame. The antenna elements are each designed to have a different length from one another so that they can receive radio waves covering a relatively broad frequency band with a relatively high sensitivity.
