Glazing having a conductive coating and a data transmission window, method of manufacturing the same and use of the same

A method for manufacturing a glazing, comprising:

• providing a pane of glass;
• depositing a conductive coating on a surface of the pane of glass;
• forming a data transmission window in or adjacent the conductive coating;
• wherein the data transmission window is at least partly coating-free;
• wherein the data transmission window comprises:
• a rectangular portion having a shorter edge and a longer edge;
• and
• a protrusion from the shorter edge or the longer edge;
• wherein the protrusion comprises:
• an axial portion having an axis parallel with the longer edge;
• and
• wherein the protrusion and the axial portion are coating-free;
• and
• wherein the rectangular portion comprises a plurality of horizontal coating-free lines having a spacing and a plurality of vertical coating-free lines having the same spacing to form a plurality of coated squares or a different spacing to form a plurality of coated rectangles;
• and
• wherein the spacing is chosen to allow transmission at a predetermined frequency through the data transmission window;
• and
• wherein the spacing is less than or equal to one tenth of a wavelength corresponding to the predetermined frequency multiplied by a shortening factor for the pane of glass;
• and
• at least a section of the axial portion having a predetermined length greater than or equal to one sixth of a wavelength of the predetermined frequency multiplied by a shortening factor for the pane of glass.
