Window assembly with transparent regions having a performance enhancing slit formed therein
First Claim
1. A window assembly for a vehicle, said window assembly comprising:
- a substrate that is substantially transparent and has a surface;
a transparent layer that is disposed on said surface and comprises a metal compound such that said transparent layer is electrically conductive;
said transparent layer defining a first region and a second region that are spaced from one another by a section cut that is devoid of said transparent layer, said first and second regions being non-congruent to one another; and
a feeding arrangement coupled to said first and second regions to energize said first and second regions;
wherein said first region defines a first performance enhancing slit that is devoid of said transparent layer; and
wherein said second region defines a second performance enhancing slit that is devoid of said transparent layer.

Abstract
A window assembly for a vehicle includes a substrate that is substantially transparent and has a surface. A transparent layer is disposed on the surface and comprises a metal compound such that the transparent layer is electrically conductive. The transparent layer defines a first region and a second region that are spaced from one another by a section cut that is devoid of the transparent layer. The first and second regions are non-congruent to one another. A feeding arrangement is coupled to the first and second regions to energize the first and second regions such that the first and second regions operate as antenna elements. The first and second regions each define at least one performance enhancing slit that is devoid of the transparent layer. The slits are configured to operate as at least one of an impedance matching element and a radiation pattern altering element.

24. A window assembly for a vehicle, said window assembly comprising:
-
a substrate that is substantially transparent and comprises an exterior substrate having an inner surface and an outer surface and an interior substrate disposed adjacent said exterior substrate having an inner surface and an outer surface; a transparent layer that comprises a metal oxide such that said transparent layer is electrically conductive, wherein said transparent layer is disposed between said exterior substrate and said interior substrate; said transparent layer defining a first region and a second region spaced from one another by a section cut that is devoid of said transparent layer; and a feeding arrangement coupled to said first and second regions to energize said first and second regions such that said first and second regions operate as antenna elements to transmit and/or receive radio frequency signals; said first and second regions being geometrically non-congruent to one another such that said first region and said second region transmit and/or receive different radio frequency signals; said first region defining a first performance enhancing slit that is devoid of said transparent layer; and said second region defining a second performance enhancing slit that is devoid of said transparent layer; wherein said first slit is configured to operate as at least one of an impedance matching element and a radiation pattern altering element with respect to said first region, and wherein said second slit is configured to operate as at least one of an impedance matching element and a radiation pattern altering element with respect to said second region.
