Abstract
A heated vehicle window includes at least one ply of a glazing material, provided with an antenna and an array of electrical conductors forming a heating circuit. The heating circuit comprises a plurality of electrical conductors and at least two busbars for supplying direct electrical current to which the electrical conductors are connected. A discrete electrically conductive layer is provided to cover at least a portion of at least two of the busbars in direct current electrical isolation therefrom. The busbars and the discrete electrically conductive layer act as a capacitor in the presence of alternating electrical current.
