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

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, comprising a plurality of first dielectric portions, interfacing the window substrate, and a plurality of second dielectric portions, each of which interfacing a respective one of the non-conductive spacers;
• a conductive layer, formed by multiple disjoined structures defined by the pattern of the non-conductive spacers, wherein:
• the multiple disjoined structures comprise a plurality of first structures and a plurality of second structures,
• each of the plurality of first dielectric portions is disposed between a respective one of the plurality of first structures and the window substrate, and
• each of the plurality of second dielectric portions is disposed between a corresponding one of the plurality of second structures and a corresponding one of the non-conductive spacers;
• a barrier layer, comprising a plurality of first barrier portions and a plurality of second barrier portions,
• such that each of the plurality of first structures is disposed between a corresponding one of the plurality of first dielectric portions and a corresponding one of the plurality of first barrier portions and
• such that each of the plurality of second structures is disposed between a corresponding one of the plurality of second dielectric portions and a corresponding one of the plurality of second barrier portions,
• wherein the barrier layer is formed from a material comprising nickel, and
• wherein each of the plurality of first barrier portions extends to and directly contacts the window substrate and forms at least a portion of a corresponding one of a plurality of sidewalls;
• and
• a second dielectric layer, disposed over the barrier layer.
