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 substantially congruent to one another and are configured to operate as diversity antenna elements. A feeding arrangement is coupled to the first and second regions to energize the first and second regions. At least one of the first and second regions defines a performance enhancing slit that is devoid of the transparent layer. The slit is configured to operate as at least one of an impedance matching element and a radiation pattern altering element.
