Embodiment Construction

[0025] Referring to the drawings, wherein like numerals indicate corresponding parts throughout the several views, the window assembly is generally figure 1 shown in 10. In one embodiment, as figure 1 As shown, the window assembly 10 is used in a vehicle 12 . Window assembly 10 may be as figure 1 The illustrated front window (windshield). Alternatively, the window assembly 10 may be a rear window (rear glass), a roof window (sunroof), or any other window of the vehicle 12 . Typically, the vehicle 12 defines an aperture and the window assembly 10 closes the aperture. The window frame 14 of the vehicle 12 is electrically conductive, the window frame 14 generally defining an aperture. The window assembly 10 may be used in applications other than the vehicle 12 . For example, the window assembly 10 may be used in architectural applications such as houses, buildings, and the like.

[0026] As shown throughout the drawings, the window assembly 10 includes an antenna element 1...

Abstract

A window assembly includes a substrate having a conductive transparent layer defining a region having a periphery. An outer zone devoid of a transparent layer is defined adjacent to and along the periphery. An elongated antenna element is arranged in the outer region. A feed element is coupled to the antenna element for exciting the antenna element. The region of the transparent layer defines at least two protrusions spaced apart from each other and extending integrally from the region and into the outer region. The antenna element adjoins and is in direct electrical contact with at least two protrusions. The feed element is coupled to the antenna element at a location between the at least two protrusions or at one of the at least two protrusions.

Description

technical field [0001] The subject invention generally relates to a window assembly. More particularly, the subject invention relates to a window assembly having a transparent layer and an antenna element. Background technique [0002] Recently, there has been an increasing need for vehicle windshields to have conductive transparent layers embedded within the windshield for various purposes, such as reflecting infrared radiation from sunlight penetrating the windshield. By doing so, the transparent layer reduces the amount of infrared radiation entering the interior of the vehicle. Therefore, during warmer months, less energy is required to reduce the temperature inside the vehicle. [0003] One or more antennas are often included on or within a windshield having such a transparent layer. Accommodating the antenna(s) is a difficult task when a transparent layer is present. First, a clear layer is typically applied over a large portion of the windshield, typically spannin...
