  • Patent number: 11335997
    Abstract: A coated window pane for rail vehicles, wherein the coating is made in a structured and electrically conductive form and includes filtering characteristics for radio signals, where the coating is structured as a conductive periodic grating, in which at least two annular coatings are respectively embedded in the intermediate spaces, the at least two annular coatings are respectively filled by a coated area, and the grating, the annular coatings and the coated areas are separated by insulating regions such that the coated, structured window panes have filtering characteristics such that signals or frequency ranges of signals from and to radio communication systems are arranged outside the vehicle pass through and signals or frequency ranges of signals from and to radio communication devices arranged inside the vehicle are blocked or are greatly attenuated, and such that high requirements with respect to heat shielding and sun shielding properties are also met.
