Embodiment Construction

[0045] exist figure 1 A radio frequency transparent solar control heat generating glazing according to the prior art is schematically represented in . A glazing 1000 in the form of a laminated glazing, such as a windshield for a vehicle, comprises on its main surface 1001 a portion 1002 whose surface is a frequency selective surface which imparts a radio frequency transparency function.

[0046] figure 2 is a cross-sectional view of portion 1002 of glazing 1000 . The glazing 1000 comprises a first sheet 2001 of transparent mineral glass and a second sheet 2002 of transparent mineral glass joined between them by means of a laminated interlayer 2004 with which they are brought into adhesive contact. The first glass sheet 2001 comprises, on its surface in contact with the lamination interlayer 2004, a layer stack 2003 comprising one or more functional metal layers (typically at least three functional metal layers), typically based on silver, which contribute to The glazing 1...

Abstract

The invention relates to a radio frequency transparent sunlight control heat generation glass window. The subject of the invention is a glazing (3000, 4000, 5000, 6000) comprising:-a transparent mineral glass sheet (3001) comprising at least one main surface (3001a); -a layer stack (3002) arranged on the main surface (3001a) of the transparent mineral glass sheet (3001), the layer stack (3002) comprising at least one functional metal layer, and at least a portion (3004a) of the layer stack (3002) being arranged according to a periodic pattern so as to form a frequency selective surface; -an electrically conductive, gridded metal grid mesh (3003) having a lower surface resistance than the surface resistance of the layer stack (3002),-the grid mesh (3003) being overlaid on the layer stack (3002) such that, in portions (3004a) of the stack arranged according to a periodic pattern, the grids of the grid mesh (3003) do not cover regions (3005) of the periodic pattern not containing the layer stack (3002).

Description

technical field [0001] The present invention relates to a radio frequency transparent solar control heat generating glazing. is used in a vehicle or in a building which allows, in particular with a low voltage supply, to at the same time ensure: a certain level of thermal comfort in the cabin of the vehicle or inside the building; Increased transmission of electromagnetic waves emitted and / or received by telecommunications equipment in telecommunication equipment; and efficient heat generation for defrosting and / or defogging of glass windows. Background technique [0002] In order to meet the increasing demand for natural lighting, transport vehicles as well as buildings are always more often equipped with surfaces mounted as glass, so that these surfaces can sometimes constitute a large part of their outer surface. [0003] In building and / or automotive applications, these glazed surfaces are generally functionalized in order to act on incident sunlight and / or infrared rad...
