ABSTRACT:
A vehicle has a window opening with a window comprising inner and outer glass layers and an interposed layer. The peripheral edge of the inner glass layer is indented in a notch which exposes an area of the outer glass layer, the space vacated by the notch being filled by an insulating member. A sealing strip, which may be electrically conducting, is disposed within the vehicle across the surface of the inner glass layer and the insulating member. An antenna is disposed between the inner and outer glass layers and has a connecting portion extending onto the exposed area of the outer glass layer. A connecting member has a connecting patch affixed to the connecting portion of the antenna within the exposed area and a feed portion extending therefrom between the insulating member and the notch of the peripheral edge of the inner glass layer to the interior of the vehicle without contacting the sealing strip. If the insulating member has a high dielectric constant, the end of the connecting member of the antenna within the exposed area is spaced away from the peripheral edge of the outer glass layer so as to minimize overlap with the sealing strip and thus capacitive coupling therebetween.
