A window assembly for a vehicle, said window assembly comprising: an exterior substrate having an inner surface and an outer surface; an interior substrate disposed adjacent said exterior substrate and having an inner surface and an outer surface with said interior and exterior substrates (20, 18) defining a first peripheral boundary; a transparent layer disposed between said inner surfaces (18a, 20a) of said exterior and interior substrates (18, 20) and defining an area covering said window assembly with said area defining a second peripheral boundary, wherein said transparent layer comprises a metal compound such that said transparent layer is electrically conductive; characterised by: an outer region defined on said window assembly between said first and second peripheral boundaries (22, 28) and being electrically non-conductive, said outer region surrounding said transparent layer such that said outer region separates said transparent layer from a window frame of the vehicle to avoid electrical path between said transparent layer and the window frame; an antenna element disposed within and surrounded by said outer region without extending across said second peripheral boundary into said area of said transparent layer; and a feeding element coupled to said antenna element for energizing said antenna element and wherein said feeding element is electrically decoupled from said transparent layer; wherein said transparent layer is not an active antenna element and reduces transmission of infrared radiation through the window assembly; and wherein said antenna element is electrically disconnected from said transparent layer such that said antenna element operates independent of said transparent layer. an exterior substrate having an inner surface and an outer surface; an interior substrate disposed adjacent said exterior substrate and having an inner surface and an outer surface with said interior and exterior substrates (20, 18) defining a first peripheral boundary; a transparent layer disposed between said inner surfaces (18a, 20a) of said exterior and interior substrates (18, 20) and defining an area covering said window assembly with said area defining a second peripheral boundary, wherein said transparent layer comprises a metal compound such that said transparent layer is electrically conductive; characterised by: an outer region defined on said window assembly between said first and second peripheral boundaries (22, 28) and being electrically non-conductive, said outer region surrounding said transparent layer such that said outer region separates said transparent layer from a window frame of the vehicle to avoid electrical path between said transparent layer and the window frame; an antenna element disposed within and surrounded by said outer region without extending across said second peripheral boundary into said area of said transparent layer; and a feeding element coupled to said antenna element for energizing said antenna element and wherein said feeding element is electrically decoupled from said transparent layer; wherein said transparent layer is not an active antenna element and reduces transmission of infrared radiation through the window assembly; and wherein said antenna element is electrically disconnected from said transparent layer such that said antenna element operates independent of said transparent layer. an outer region defined on said window assembly between said first and second peripheral boundaries (22, 28) and being electrically non-conductive, said outer region surrounding said transparent layer such that said outer region separates said transparent layer from a window frame of the vehicle to avoid electrical path between said transparent layer and the window frame; an antenna element disposed within and surrounded by said outer region without extending across said second peripheral boundary into said area of said transparent layer; and a feeding element coupled to said antenna element for energizing said antenna element and wherein said feeding element is electrically decoupled from said transparent layer; wherein said transparent layer is not an active antenna element and reduces transmission of infrared radiation through the window assembly; and wherein said antenna element is electrically disconnected from said transparent layer such that said antenna element operates independent of said transparent layer.
