Abstract
An antenna suitable for use in the 5 GHz WLAN/Wi-Fi and DSRC frequency band is integrated with a vehicle window that is includes outer and inner transparent plies bonded together by an interlayer. The inner transparent ply and the interlayer serve as an antenna substrate. A first conductive layer is formed on the inner surface of the outer transparent ply and a second conductive layer that defines a coupling slot is formed on the outer surface of the inner transparent ply. The antenna may be excited by a coaxial cable or a microstrip line that crosses the coupling slot.
