Embodiment Construction

[0045] It should be noted that the present invention may incorporate more than two antennas. Although the invention is described with respect to AM, FM, DAB and IV antennas on glass, this should not be considered limiting. The invention is applicable to other situations where electromagnetic energy is employed and it is desired to send or receive electromagnetic energy.

[0046]The invention is applicable to glazing comprising at least one layer of plastic material, such as laminated glass and double glazing (ie a layer of glass plus a layer of plastic). Such glazing may further comprise layers of plastic glazing, annealed, tempered or tempered glass, coated glazing, wired glazing and combinations thereof.

[0047] Throughout the drawings, the same elements serving the same purpose are provided with the same reference numerals.

[0048] refer to figure 1 , in the present invention, the substantially flat glazing 10 includes a glazing material layer 11 . A layer 12 of plast...

Abstract

A compact arrangement of antennas in a glazing is disclosed, which allows a plurality of antenna wires to be connected to an external circuit by a single contact. Parallel conductors (14, 15), in direct current isolation from each other so that alternating current coupling occurs between them, are embedded at different depths in the thickness of a ply of plastic material. In plan view, conductors at different depths may be positioned closer to each other than in the prior art, so antennas connected to them are less obtrusive and may even be hidden completely under an obscuration band. Different widths of parallel conductor may be used. A thin antenna, connected to a thin conductor, may be positioned in a vision area of a glazing without impeding the view.

Description

Background technique [0001] The invention relates to a glazing having a layer of plastic material in which an antenna is embedded. [0002] As eg more communication systems are required in vehicles, the number of antennas in the glazing is increased. Such communication systems in vehicles include radio (AM, FM), digital audio broadcasting (DAB), television (IV), digital video terrestrial broadcasting (DVB-t), telephone (GSM), navigation (GPS), WLAN , remote keyless entry (RKE), car-to-car communication and car-to-infrastructure communication (car2X) and paging systems. For all of these communication systems, it is desirable to have a separate optimized antenna that needs to be connected to the electronics within the motor vehicle, which is usually located away from the glass windows. Numerous proposals to provide such antennas and connections have been made in the art. [0003] DE4415675C1 discloses a glazing comprising a layer of plastic material used as an interlayer for ...
