Le verre à faible émissivité comprend : un substrat ; et un film à structure empilée qui recouvre au moins une surface du substrat, le film à structure empilée comprenant une couche de réflexion infrarouge métallique et une pluralité de couches diélectriques, la couche de réflexion infrarouge métallique ayant une pluralité d'ouvertures. La vitre de véhicule comprend une encapsulation et le verre à faible émissivité. Le procédé de fabrication du verre à faible émissivité consiste à : prévoir un substrat ; et recouvrir au moins une surface du substrat avec un film à structure empilée, le film à structure empilée comprenant une couche de réflexion infrarouge métallique et une pluralité de couches diélectriques, le recouvrement avec le film à structure empilée comprenant la formation d'une pluralité d'ouvertures dans la couche de réflexion infrarouge métallique. L'avantage de la présente invention est que la pluralité d'ouvertures favorisent le passage des signaux sans fil qui traversent ladite pluralité d'ouvertures, ce qui permet de réduire l'effet de blindage du verre à faible émissivité sur les signaux sans fil. Par conséquent, le verre à faible émissivité selon la présente invention permet non seulement de bloquer les rayons infrarouges, mais également d'augmenter la transmittance des signaux sans fil à travers le verre à faible émissivité.
