Antenna-embedded laminated glass and method for preparing the same

Abstract

The present invention provides a method for preparing an antenna-embedded laminated glass with an antenna element sealed between glass sheets, which is characterized to comprise forming two or more glass sheets forming the laminated glass; bonding a transfer film on a surface of one of the glass sheets by a bonding strip, the transfer film including the bonding strip and a conductive strip forming the antenna element; and press-bonding glass sheet, through a intermediate film, to the surface of the one glass sheet with the transfer film bonded thereto.

1 . A method for preparing an antenna-embedded laminated glass, comprising:
 forming a plurality of glass sheets in a curved shape;   laminating the glass sheets, an antenna element and an intermediate film to form a laminated structure with the intermediate film interposed between adjacent glass sheets, the intermediate film affixing the antenna element and the adjacent glass sheets; and   press-bonding the laminated structure;   wherein the laminating step comprises forming the laminated structure by bonding a transfer film to form a conductive strip on a surface of at least one of the glass sheets by use of a bonding strip, and detaching a detachable layer from said transfer film before performing the laminating step so that only the conductive strip and the bonding strip remain on a mating surface of the glass sheets,   the transfer film including the bonding strip and the conductive strip, wherein the detachable layer is disposed on said transfer strip on a side of the bonding strip,   the conductive strip forming the antenna element, the surface confronting the intermediate film.
