Energy-efficient window coatings transmittable to wireless communication signals and methods of fabricating thereof

An energy-efficient signal-transparent window assembly comprising:

• a window substrate;
• a first layer disposed over the window substrate;
• a conductive layer disposed over the first layer such that the first layer is disposed between the conductive layer and the window substrate, wherein the conductive layer is formed by multiple disjoined structures separated by gaps;
• and
• a second layer disposed over the conductive layer such that the conductive layer is disposed between the second layer and the first layer, wherein:
• the first layer, the conductive layer, and the second layer form a plurality of primary stacks, each comprising two sidewalls and separated from each other by the gaps,
• the gaps form a pattern, defined by pattern lines, and
• each of the pattern lines has a width larger than the gaps separating the multiple disjoined structures by between 0.4 and 6 micrometers.

An energy-efficient signal-transparent window assembly comprising:

• a window substrate;
• non-conductive spacers, forming a pattern on the window substrate, interfacing a portion of the window substrate, and blocking the portion of the window substrate;
• a first dielectric layer, interfacing the window substrate and the non-conductive spacers;
• a conductive layer, disposed over the first dielectric layer such that the first dielectric layer is disposed between the conductive layer and each of the window substrate and the non-conductive spacers;
• a second layer disposed over the conductive layer such that the conductive layer is disposed between the second layer and the first layer;
• and
• non-conductive structures positioned within the conductive layer and forming a plurality of primary stacks and a plurality of secondary stacks, wherein:
• the first layer, the conductive layer, and the second layer form a plurality of primary stacks and a plurality of secondary stacks over at least a portion of the window substrate,
• the plurality of secondary stacks forms a pattern, defined by spacer pattern lines, partially on the window substrate and partially on a top surface of the plurality of primary stacks, and
• the spacer pattern lines comprise a top surface and a side surface,
• stacks of the plurality of secondary stacks are broken on the top surface or the side surface of the spacer pattern line thereby physically isolating the stacks and discontinuing the conductive layers along the spacer pattern lines.
