Abstract

A laminated glass pane, such as a front pane for a motor vehicle, includes at least two glass layers including a first glass layer and a second glass layer. The laminated glass pane includes a film disposed between the first and second glass layers. The laminated glass pane includes a metallic layer disposed on the first glass layer or the second glass layer, in which the metallic layer includes a recess. The laminated glass plane includes a first black print grid at least partially covering the recess of the metallic layer. The laminated glass plane includes an antenna structure disposed between the first and second glass layers, in which the antenna structure is covered by the first black print grid.

DETAILED DESCRIPTION OF THE FIGURES

[0030] In the figures, the same structural elements each have the same reference numerals.

[0031] FIG. 1 shows a perspective view of a laminated glass pane 1 according to an embodiment of the present invention in the region of the mirror base plate bracket 2 according to a first embodiment of the present invention. The laminated glass pane 1 has a black print grid 4 in the region of the mirror base plate bracket 2. An antenna 6 or an antenna structure 6 is integrated in the black print grid 4. In FIG. 1, the antenna 6 is shown highlighted for clarity. In this case, the antenna structure 6 may have the same shape as the black print grid 4. By overlaying the black print grid 4 on the antenna structure 6, the antenna structure 6 can be concealed or covered. As a result, the antenna structure 6 arranged in the region of the mirror base plate bracket 2 on or in the laminated glass pane 1 is imperceptible, for example, to a driver.

[0032] FIG. 2 shows a schematic cross section of a laminated glass pane 1 according to a further embodiment of the present invention. Here, the laminated glass pane 1 is shown in the region of the mirror base plate bracket 2. According to the exemplary embodiment, a film 12 and an antenna structure 6 are arranged between a first glass layer 8 and a second glass layer 10 between two black print grids 4. The film 12 serves for mechanically reinforcing the laminated glass pane 1. The antenna structure 6 is here covered on both sides by a respective black print grid 4. For electrically connecting the antenna structure 6 to an electrical connection or line 16, the antenna structure 6 has at least one contact point 14. According to the exemplary embodiment, the black print grid 4 and the antenna structure 6 are protected on both sides by the first glass layer 8 and the second glass layer 10.

[0033] FIG. 3 shows a schematic cross section of a laminated glass pane 1 according to a further embodiment of the present invention. In contrast to the laminated glass pane 1 already shown in FIG. 2, the antenna structure 6 with the black print grids 4 arranged around the antenna structure 6 on both sides is not positioned between the two glass layers 8, 10 but on an outer surface of the second glass layer 10. In this way, a conventional laminated glass pane can be retrofitted with an antenna structure 6 concealed on both sides by a black-and-white print grid 4.

[0034] FIG. 4 shows a schematic cross section of a laminated glass pane 1 according to a further embodiment of the present invention. In contrast to the embodiments of the laminated glass pane 1 already shown, the antenna structure 6 concealed on both sides by a respective black print grid 4 is arranged here between the first glass layer 8 and the film 12. In this case, the respective black print grid 4 and the antenna structure 6 can be arranged between the first glass layer 8 and the second glass layer 10 in the context of a manufacturing process of the laminated glass pane 1.

[0035] FIG. 5 shows a schematic cross section of a laminated glass pane 1 according to a further embodiment of the present invention. In contrast to the embodiment of the laminated glass pane 1 shown in FIG. 4, the antenna structure 6 in this case is only covered on one side by a black print grid 4. The antenna structure 6 is colored here with a color of the black print grid 4, so that the antenna structure 6 is imperceptible on both sides despite concealment on one side by a black print grid 4.
