A heatable article, e.g. a heatable windshield, having a generally
trapezoidal shape has a conductive member, e.g. a conductive coating,
between and in contact with a pair of spaced bus bars having different
lengths. Selected portions of the coating between the bus bars are
segmented to reduce the difference in watt density between the coatings
at the bus bars when current moves through the coating. In one
non-limiting embodiment, the width of the segments at the longer bus bar
is less than the width of the segments at the longer bus bar. With this
configuration, the watt density at the bottom of the windshield is
increased to more efficiently remove ice and snow. In another
non-limiting embodiment, the coating has a communication window to pass
frequencies of the electromagnetic spectrum, e.g. RF frequencies, to
obtain information from within the vehicle. The coating surrounding the
conductive window has break lines to segment the coating to eliminate hot
spot around the periphery of the communication window.
