Abstract
A slot antenna in a heatable vehicle glazing established between the heating bus bar, bus bar extensions and the peripheral edge of an IR reflective coating. The antenna slot may be fed directly by a voltage source, a current source, or a coupled coplanar line at locations that excite both fundamental and higher order modes for multiband antenna applications. The slot antenna may be established between split bus bars or split bus bar extensions that limit heat loss and improve antenna efficiency. Multiple antennas can be integrated into the heatable glazing for multiband applications and/or diversity antenna systems.
