Description
The present invention relates to a glass sheet for transportation vehicles and the use thereof.
Vehicles are increasingly being equipped with electrical components. In addition to conventional radio devices, an increasing number of devices which can receive or transmit high-frequency signals are being found in vehicles.
In this connection, signals of a navigation system or signals of a communication system can be cited as an example.
The navigation system may be, for example, a satellite-assisted navigation satellite system (GNSS). The system in operation is for example the Global Positioning System (GPS) or the global navigation satellite system (glonass). Other navigation systems may be based on mobile radio systems, for example.
The communication system may be a short range radio system, e.g. for car-to-car or car-to-infrastructure, or a mobile radio communication system, e.g. a 2/3/4 or 5 th generation mobile communication system.
Since vehicles often have large metal surfaces, high frequency signals are shielded and thus difficult to receive (and transmit if provided).
Although it is possible to fix the respective antenna externally on the vehicle, such an attachment is problematic from a multiple point of view.
An exemplary arrangement is known from US 20140176374 a 1.
On the one hand, corresponding devices require through-holes (Durchbr üche), which are susceptible to corrosion. On the other hand, such devices often disturb the visual impression. However, such devices often also provide a source of noise and increased wind resistance. Furthermore, such antennas are also targets for vandalism.
Based on this, a trend of providing antennas at other positions has been developed in the past.
For example, the GNSS antenna may be arranged within a vehicle interior space, for example under the dashboard or under the windshield.
It is difficult to find a suitable position with a good antenna view for GNSS satellites and at the same time avoid EMC problems due to electrical equipment in the instrument panel and due to the vehicle engine.
In addition, conductive layers such as infrared reflective layers or low-E layers may prevent electromagnetic radiation from transmitting through the glass sheet and blocking GNSS signals.
Typical GPS antennas are implemented as planar antennas and typically as patch antennas and are known, for example, from WO 00/22695 a1, DE 202006011919U 1 or DE 202010011837U 1. In this case, the planar metallic antenna structure is arranged on one side of a printed circuit board or a ceramic carrier. A planar substrate is arranged as a ground plane on the opposite side. The antenna structure and the substrate are connected to the electrical receiving unit by electrical leads. Due to the material thickness of the printed circuit board or the ceramic carrier, the antenna has a certain thickness and is clearly visible and not very aesthetically pleasing when arranged directly on the windshield.
A vehicle glazing with an integrated GPS antenna is known from international patent application WO 2016/162251 a1, which is coupled by coplanar strip conductors.
In the case of the applicant's product, there is also provided an antenna on or in a glass sheet. However, it has been shown that connecting such an antenna to a system remote from a glass pane is not without problems.
Typically, the antenna structure and the strip conductor structure are positioned on the glass pane in such a way that a film F with a strip conductor is laid around the edge of the glass pane GS1 in the edge region of the glass pane. However, the fixing region for the glass pane on the vehicle body a is also in the same region. The adhesive KL (polyurethane based) is often also in this fixing region. In addition to the actual antenna conductor, the former strip conductor structure provides a conductor for the ground plane GND (housing potential) parallel thereto in the same structural plane.
In a fixed area, especially at high frequencies (> 500 MHz, especially 1 GHz), signal attenuation occurs on the strip conductor.
This weakening may be due to the adhesive KL and its electric field constant and/or another GND potential (housing potential) spatially close to the vehicle body a.
The object of the invention is to provide an improved glass pane for a vehicle, in which an antenna, in particular a GPS antenna, and a connection structure with improved properties can be integrated in a simple and cost-effective manner.
According to the invention, the object of the invention is achieved by a glass pane for a vehicle according to independent claim 1. Preferred embodiments emerge from the dependent claims, the figures and the description.
The glass pane for a vehicle according to the invention has at least one first glass layer, wherein a film having two conductor layers is applied to the first glass layer, wherein an antenna structure is provided by means of at least one of the two conductor layers, wherein a connection structure to the antenna structure is provided by means of the two conductor layers, wherein the connection structure has a central conductor, to the two side conductors of which two side conductors are arranged, wherein the central conductor and the two side conductors arranged on both sides are located in one of the two conductor layers, wherein a conductor is provided in the other of the two conductor layers, which conductor is arranged substantially parallel to the central conductor and the two side conductors arranged on both sides, wherein the two side conductors arranged on both sides and the conductor have substantially the same potential.
By means of the invention, the disturbing influence in the fixed area can be reduced, thus providing less signal attenuation.
In one embodiment of the invention, the film is turned around the first glass layer in the region of the connection structure.
The film with the antenna structure can thus be arranged on one side of the glass pane, while the joining region can be arranged, for example, at the connection structure on the inside.
In another embodiment of the invention, the film is flexible. In another embodiment of the present invention, the thin film has a thickness of 25 μm to 500 μm.
This can easily provide bending, e.g. turning around the glass layers, without having to pre-form them.

Improved potential equality (potential equality) is achieved over this arrangement by means of the metallized vias, so that the high-frequency performance can be further improved.
According to a further embodiment of the invention, at least one of the two conductor layers has at least partially a cover layer.
Contact possibilities can thus be established at suitable points with one of the conductor layers or its structure, for example to provide a connection to the housing potential. On the other hand, undesired contact can be prevented by the cover layer.
In another embodiment of the invention, the antenna structure is arranged for receiving high frequency signals. In particular, the antenna structure may be arranged for receiving mobile radio communication signals and/or signals of a (satellite-assisted) positioning system.
In another embodiment of the invention, the film has at least one material selected from the group consisting of: polyimide, polyurethane, polymethylene methacrylic acid, polycarbonate, polyethylene terephthalate, polyvinyl butyral, FR6, acrylonitrile-butadiene-styrene copolymer, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polybutylene terephthalate, polyamide.
That is to say, materials which are suitable on the one hand as a support for the conductor structures during production and which are optionally optically transparent and/or can optionally be readily connected to the glass layer can be used.
In fact, all electrically insulating substrates which are thermally and chemically stable under the conditions of the manufacture and use of the glass panes according to the invention as vehicle glazing are suitable as glass panes.

According to another embodiment of the invention, the glass pane is a composite glass pane (Verbundglasscheib), wherein the glass pane has a second glass layer, wherein a thin film is introduced between the first glass layer and the second glass layer.
In other words, the film can be introduced both on the outer side of the glass pane and between the glass layers of the composite glass pane.

In which different embodiments are shown.
A glass pane for a vehicle is shown in fig. 1 in an installed state. The glass sheet has at least one first glass layer GS 2.

At least one of the conductor layers is structured, as described below. The structuring can be produced by different processes, for example by corresponding (screen-) printing, (ablative) laser structuring, (wet chemical) etching, etc.
The antenna structure ANT is provided by means of at least one LS1, see fig. 4, of the two conductor layers.
The antenna structure ANT in fig. 4 may itself be suitably selected and has, for example, a horn antenna, a polarized antenna, a broadband antenna, etc.
Furthermore, the connection structure GCPW for the antenna structure is provided by means of two conductor layers LS1, LS 2. The connection structure GPCW has a central conductor ML on one film side, on both sides of which two side conductors L1, L2 are arranged, wherein the central conductor ML and the two side conductors L1, L2 arranged on both sides are located in one of the two conductor layers, here in the conductor layer LS 1. In the other conductor layer LS2 of the two conductor layers, a conductor GL is likewise provided, which is arranged substantially parallel to the central conductor ML and to the two side conductors L1, L2 disposed on both sides, wherein the two side conductors L1, L2 disposed on both sides and the conductor GL have substantially the same potential.

The width occupied by conductor GL in further conductor layer LS2 is generally greater than width b of central conductor MLMLA distance a from each of the two side conductors L1, L2 to the center conductor ML1，a2The sum of the widths of (a) and (b).
By means of the invention, the disturbing influence in the fixed area can be reduced, thus providing less signal attenuation.
In one embodiment of the invention, the film F is turned around the first glass layer GS2 in the area of the connection structure GCPW-as shown in fig. 1.
The film F with the antenna structure ANT can thus be arranged on one side of the glass pane GS2, while the joining region S can be arranged, for example, at the connection structure GPCW on the inner side of the glass pane GS 2.
In another embodiment of the invention, the film F is flexible. In another embodiment of the present invention, the thickness h of the filmFIs 25 μm to 500. mu.m.

Thereby not adversely affecting optical performance. It should be noted that the conductor structures GPCW and/or the antenna structures ANT are not arranged in the optically visible region in all applications, but it is also possible to arrange these structures in the edge regions, which are usually optically opaque due to the black print. In this case, the transparency of the film F and/or of the conductor layers LS1, LS2 need not be taken into account.
In a further embodiment of the invention, each of the two side conductors L1, L2 is at a distance a from the center conductor ML1, a2Is 50 μm to 300 μm at the minimum. It should be noted that the distances a1, a2 do not necessarily have to be the same, but may also be different. However, it is preferred that the distances are the same, i.e., a1= a2。
In another embodiment of the present invention, the width b of the center conductor MLMLIs 50 to 300 mu m. The width of the central conductor ML can depend on the material used for the conductor layer LS1 and/or the frequency of the signal to be conducted.
According to another embodiment of the present invention, the conductor layer hLS1, hLS2Is 1 μm to 75 μm, preferably 10 μm to 75 μm. It should be noted that the height hLS1, hLS2Not necessarily the same, but may be different. However, it is preferred that the heights are the same, i.e., hLS1= hLS2。
That is, the present invention can realize a fine structure suitable for high frequencies as well.
According to another embodiment of the invention, one or more metallized VIAs VIA are arranged at least between one of the side conductors L1 and the conductor GL situated opposite with respect to the film F-as shown in fig. 3. Here, the metalized VIAs VIA may be arranged at a predetermined distance. In addition, a metallized VIA may also be provided in a similar manner with respect to second side conductor L2 and oppositely located conductor GL. The distance may be dependent on the wavelength of the signal to be conducted. Furthermore, the wave impedance of the connection structure GCPW can be matched by such a metallized VIA. Furthermore, an improved potential equality is achieved within the scope of the arrangement by means of the metallized VIA, so that the high-frequency performance can be further improved.
According to a further embodiment of the invention, at least one of the two conductor layers LS1, LS2 has a cover layer (at least) in part.
Contact possibilities to one of the conductor layers LS1, LS2 or to its structure (L1, L2, ML, GL) can thus be established at suitable points, for example to provide a connection to the housing potential GND. On the other hand, undesired contact can be prevented by the cover layer.
In another embodiment of the invention, the antenna structure ANT is arranged for receiving high frequency signals. In particular, the antenna structure ANT may be arranged for receiving mobile radio communication signals and/or signals of a (satellite-assisted) positioning system.
In another embodiment of the invention, the film F has at least one material selected from the group consisting of: polyimide, polyurethane, polymethylene methacrylic acid, polycarbonate, polyethylene terephthalate, polyvinyl butyral, FR6, acrylonitrile-butadiene-styrene copolymer, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polybutylene terephthalate, polyamide.
That is to say, materials which are suitable on the one hand as a support for the conductor structures during production and which are optionally optically transparent and/or can optionally be readily connected to the glass layer can be used.
In a further embodiment of the invention, the conductor layers LS1, LS2 comprise silver and/or copper and/or gold and/or aluminum and/or indium and/or graphene. It should be noted here that the conductor layers LS1, LS2 may be of different materials. However, they are preferably of the same material. That is, the conductor structure may also be matched to electrical and/or thermal and/or mechanical boundary conditions.
According to a further embodiment of the invention, the connection structure GCPW, as shown in fig. 1, has a coupling region S for electromechanical high-frequency connection elements. In particular, the connection structure may have an SMA socket. The SMA sockets may have, for example, an angular arrangement to provide a low build height (Bauh ribbon) in the coupling area. Usually, the vehicle glazing is equipped as an assembly/replacement part with electromechanical high-frequency connection elements S, in order to be able to be assembled quickly and to be contacted reliably.
According to another embodiment of the invention, the glass pane is a composite glass pane, wherein the glass pane has a second glass layer GS1, wherein the film F is introduced between the first glass layer GS2 and the second glass layer GS 1. In other words, the film can be introduced both on the outer side of the glass pane and between the glass layers of the composite glass pane. In this case, the film F (with the respective conductor layers LS1, LS2) can be applied directly to one of the glass layers GS1, GS2, or intermediate layers VF can be arranged above and/or below the film F (with the respective conductor layers LS1, LS 2). The intermediate layer VF is used mainly to connect the glass layers GS1 and GS 2. In order to compensate for the height differences due to the films F (with the respective conductor layers LS1, LS2), the intermediate layer VF can have recesses. The intermediate layer VF comprises at least one material chosen from: polybutylene terephthalate (PBT), Polycarbonate (PC), polyethylene terephthalate (PET) and polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl fluoride (PVF), polyvinyl butyral (PVB), Ethylene Vinyl Acetate (EVA), Polyacrylate (PA), polymethyl methacrylate (PMMA), Polyurethane (PUR) and/or mixtures and copolymers thereof.
According to another embodiment of the present invention, a vehicle, in particular a land vehicle, a marine vehicle, an air vehicle or a space vehicle (or a combination thereof), is provided having a glass sheet according to the present invention.
According to a further embodiment of the invention, the glass pane according to the invention is used for receiving signals for satellite-assisted navigation, in particular for receiving GNSS signals of Navstar GPS, galileo, glonass, beidou, Navic, QZSS. Alternatively or additionally, a glass pane according to one of the preceding claims 1 to 18 according to the invention is used for receiving signals of a mobile communication system, in particular of a2 nd, 3 rd, 4 th or 5 th generation mobile communication system.
As a result, a new approach is sought to replace the prior art techniques of transmission lines or coplanar waveguides used in the prior art. By using conductors GL located opposite, the influence of interfering elements can be reduced, in particular in the fixed area.
The requirement for a thin structure that can be integrated is still met here.
By means of the invention, good transmission can be provided with a good matching of the waveguide impedance also in case of bending around the glass layer GS 2.
This result is unexpected and surprising to those skilled in the art.
