Estimating the term…
A pair of antenna elements are mounted on a glass of a rear quarter window of a vehicle. Feed points of these elements are provided at a corner portion of the window. One antenna element extends clockwise about the center of the window glass and the other antenna element extends counterclockwise thereabout from their corresponding feed points. The characteristics of both antenna elements significantly differ and complement each other. It is convenient for a diversity reception system. An auxiliary element branches from one antenna element to extend along the other antenna element. The auxiliary element compensates for impedance characteristics of the antenna elements to tune up reception characteristics thereof.
A window antenna mounted on a glass of a rear quarter window of a vehicle, comprising a pair of antenna elements and feed points of said antenna elements, these feed points being arranged at one corner portion of the window, and one antenna element extending clockwise about the center of the window glass and the other antenna extending counterclockwise thereabout, from their corresponding feed points wherein said pair of antenna elements are incorporated in a diversity reception system.
