A glazing comprising a transparent substrate, a plurality of electrically conductive filaments extending over the transparent substrate, wherein the filaments are shaped into a sequence of portions of the perimeters of ellipses, wherein ellipse axial ratios of the ellipses are in the range 1.1 to 4.0 and are selected so that from a pre-defined viewing position and in corresponding pre-defined viewing directions the ellipses in the plane of substrate are viewed as circles. In a preferred embodiment, major axis angles are selected so that from a pre-defined viewing position and in corresponding pre-defined viewing directions the ellipses in the plane of substrate are viewed as circles. In an example of a heated vehicle window, diffraction patterns caused by oncoming headlights interacting with heating filaments of a vehicle window are thereby minimized.
