    Conductively coated window pane, in particular for rail vehicles
    Technical area
    The present invention relates to a coated window pane, in particular for rail vehicles, wherein the coating is structured and electrically conductive and has a filter characteristic for radio signals.
    State of the art
    In vehicles such as Passenger rail vehicles are subject to availability of current communication services, such as mobile voice communication, mobile data communication, etc. based on e.g. GSM, UMTS and LTE, increasingly demanded. Therefore, the best possible reception level and a corresponding reception quality in vehicles, in particular public transport such. Trains, trams, etc. asked.
    An obstacle to a good reception are conductive coated windows in these vehicles. The coating is used as heat and sun protection. However, not only the heat radiation or the sun's rays are reflected by the coating of the window panes, but also other electromagnetic waves such. the electromagnetic waves for mobile communication services of radio communication devices.
    The vehicle thus has a high transmission loss for electromagnetic waves and acts like a Faraday cage. For example, with the Intercity Express or ICE, the attenuation is around 30 dB. The shielding is thus about 99.9%.
    Instead of a waiver or reduction of the coating and thus a reduction or a cancellation of the heat and sun protection effect are known from the prior art such. For example, http: / / en - wikipedia, org / wiki / I ntra.in repeater so-called in-train repeater to overcome the insertion loss known. By in-train repeater to a communication between a mobile device (eg mobile phone, tablet PC, smartphone, etc.) and a wireless communication device, which is located outside the vehicle (eg mobile network, etc.) to improve and a trouble-free communication as possible be enabled.
    Without an in-train repeater, interference-free use of mobile communication services or interference-free connection without crashes would only be possible in those areas having sufficiently high field strength to protect the shielding of vehicles such as e.g. overcome by modern passenger trains. This is usually the case in metropolitan areas and at railway stations. Especially in rural areas, the radio communication devices such as e.g. Mobile networks based on the GSM or UMTS standards are not as strong or dense. As a result, a supply or corresponding connection to radio communication devices of vehicles or individual cars without in-train repeater is not always guaranteed.
    From document DE 195 03 892 CI or from document EP 2 586 610 A1, e.g. Window panes are known for use in vehicles (e.g., power tools, etc.) which increase the reception level of mobile terminals (e.g., cellular phones, etc.) in the interior of a vehicle, even without the use of a repeater. These windows are provided with an electrically conductive, transparent layer. The conductive layer is e.g. applied by steaming on the disc and structured. The structuring of the layer is designed such that radio signals can pass as unhindered as possible in certain frequency ranges.
    In order to provide communication services, in particular mobile data services, in vehicles such as e.g. the ICE of the German Railways or the Railjet of the Austrian Federal Railways, etc., nowadays a wireless internet access is offered for example in these vehicles. For this purpose, e.g. the vehicle or train is equipped with Wireless Local Area Network or WLAN technology (Wi-Fi hotspots connected to the Internet via a server and the shore-side mobile stations), so that the mobile data services or the wireless Internet in all wagons of the However, signals from radio communication devices located outside the vehicle and using the same frequency range can interfere with the communication quality of the WLAN connection within the vehicle. Furthermore, for example, communication services offered in a vehicle, which could be e.g. are offered to passengers free of charge, also be used from outside the vehicle. In addition, radio communication devices outside the vehicle may also be disturbed by the radio signals of the in-vehicle radio communication systems.
    From WO 2014/166869 a coated window pane is known in which the coating is frequency-selective. The coating in this case has a filter characteristic such that signals or frequency ranges of signals from and to radio communication systems which are arranged outside the vehicle are transmitted, and in that signals or frequency ranges of signals from and to radio communication devices which are arranged inside the vehicle, locked or strongly attenuated.
    For this purpose, the coating has a structuring with structural elements.
    Presentation of the invention
    The invention has for its object to further develop the state of the art.
    The solution of this task is carried out with a coated window pane according to claim 1.
    Advantageous embodiments emerge from the subclaims
    Brief description of the drawing
    The invention will be explained in more detail with reference to two figures. They show by way of example and schematically:
    1 shows the structure of the coating of a window pane according to the invention based on a rectangular grid, and FIG. 2 shows the structure of the coating of a window pane on the basis of a hexagonal grid
    Embodiment of the invention
    Figure 1 shows schematically and by way of example a section of a conductive coated window pane according to the invention, which can be used advantageously in vehicles such as rail vehicles, but also in windows of stationary objects. The window pane has an electrically conductive and largely transparent coating, which is frequency-selective owing to its structuring according to the invention, that is to say that it has high throughput for radio signals of a specific frequency band and dampens radio signals at a different frequency.
    The coating takes place, for example, with metals or metal oxides, but other materials are also conceivable.
    By means of the appropriate design of the structuring of the coating, signals from and to the radio-communication equipment, e.g. Mobile networks according to the GSM, UMTS or LTE standard or possibly also signals from GSM-R networks, DVB-T, FM
    Radio waves or BOS radio system such as e.g. TETRA allowed through. On the other hand, signals from and to radio communication devices, e.g. Wireless LAN locked.
    According to the invention, the coating has the structure of a conductive periodic grating RG, HG, in each of which at least two annular coatings R are inscribed, and wherein the at least two annular coatings R are each filled by a coated surface F and the grating RG, HG, the annular coatings R and the coated surfaces F are separated by insulating regions.
    In the embodiment of FIG. 1, the periodic grating is constructed as a rectangular grid RG. Each rectangle has a square shape and comprises four equally square annular coatings R, each of which encloses a square area F.
    It should be noted that the term ring, or annular coating R includes not only circular shapes, but also a closed polygon, which surrounds a square in the present embodiment, but in other possible embodiments, for example, also have the shape of a triangle, hexagon or a rhombus can.
    In addition, a ring may have different widths, i. it is then defined by an inner and an outer closed polygon, which may have different shapes. For example, the inner traverse of a ring could be square, while the outer traverse could be hexagonal, and so on.
    The rectangular grid RG, the annular coatings R in the form of a closed square polygon and the coated surfaces F are separated from each other by insulating regions I. In the figure, the insulating ones
    Regions I represented by the black lines, while the bright areas represent the coatings.
    Structures are also conceivable in which further rings are inscribed inside the first ring R. The innermost ring is then replaced by a coated, e.g. metallized area F filled.
    Fig. 2 shows an embodiment in which the periodic grating is constructed as a hexagonal grid HG. Each hexagon comprises in the embodiment 3 diamond-shaped polygons as rings R, each of which has a diamond-shaped coated, e.g. metallized surface F encloses.
    The geometry for a structure for a particular application with given radio characteristics of the coated window pane, i.A. a frequency transmission characteristic, can be with the knowledge of the used disk structure, the data of the coating, i.A. a surface resistance and line widths, which are still optically acceptable and manufacturable, determine by field simulation.
    Typical output data are, for example:
    The frequency characteristic: passband e.g. between 700 MHz and 2.7 GHz (for LTE, GSM, and UMTS frequencies) with attenuation less than 10 dB. Stop band, e.g. between 5.2 and 5.8 GHz (for WLAN / WiFi) with attenuation greater than 20 dB - The angle dependence: The required frequency characteristic is maintained for an incident angle range of -45 ° to + 45 ° over all spatial directions. - The pane structure: Glass thickness of the outer and inner glass between 3 mm and 10 mm with a relative dielectric constant of 4 to 8. The glass can be single-layer (ESG) or multilayer (VSG) and layers of plastic (eg films of PVB contain). Plastic can also be used instead of glass, which typically reduces the dielectric constant. Gap between the glass elements is typically 8 to 20 mm. The discs can be bent or flat. - The structuring: A structuring of the coating with gap widths smaller than approx. 0.5 mm is typical and reduces the optical perceptibility.
    The inventive structure of the coating allows good transmission properties at low frequencies and a stopband at high frequencies.
    The more ring elements R are inserted within the inter-grid spaces, the smaller these elements become and the higher the rejection frequency. The ratio of the high blocking frequency and the lowest low transmission frequency can be selected, for example, at about 8. As a result, a passband from 700 MHz and a stopband at 5.5 GHz can be achieved. Relative 3dB bandwidths of the passband of over 100% can be achieved.
    The number and design of the ring elements R within the grid interspaces is therefore of particular importance for the design of the filter characteristic. They offer the possibility to adapt the filter characteristics of the windows in a particularly advantageous manner to a wide variety of conditions.
    In order to let pass the lowest transmission frequency, the grating RG, HG must be designed so large that the mesh size corresponds to about a quarter of the wavelength.
    Here, however, not the free wavelength is used, but the effective wavelength, which is reduced by the influence of the glass elements.
    The surface elements F within the rings R are chosen in size so that they come in self-resonance at the blocking frequency, so about half an effective wavelength are large.
    Different sizes and shapes of the surface elements F located in the grid gap can be selected to achieve fine shaping of the blocking characteristic.
    The rings (polygons) R serve the purpose of reducing the mutual interference of grids RG, HG and surface elements F. They reduce the attenuation in the passband, which connects up to the minimum transmission frequency. Only through the rings R, the high relative bandwidths in the passband possible.
    The coating of the window panes can also be provided with a fine structure, by which the properties in the optical and thermal range are changed. By means of the fine structure, for example, an appearance of the windows can be designed accordingly. For example, attractive structural patterns, shapes, logos, etc. can be realized.
    In a vehicle, the coated windows can be arranged distributed over the sides of the vehicle. In this way, in the context of the achieved frequency-selective transmission characteristic, the reception conditions are designed deliberately both for the radio communication devices arranged outside the vehicle and for the radio communication devices arranged inside the vehicle.
    Likewise, the windows of the present invention may also be used in other vehicles (e.g., buses, etc.) and in buildings with coated windows.
