Description

Laminated glass and method for producing laminated glass Technical Field The present invention relates to laminated glass and a method for producing laminated glass. Background Recently, with commercialization of wireless communication services between vehicles such as C-V2X (Cellular Vehicle to Everything communication, cellular internet of vehicles communication), devices for supporting these new services are also provided in vehicles. The shark fin antenna for wireless communication may be configured on a vehicle. The shark fin antenna is capable of receiving electrical signals such as 4G (LTE), eCall, ISM wireless communication band, GPS/GNSS, DMB/DAB/ISDB-T, etc. Since the shark fin antenna is a structure attached to the outside of the vehicle, there are troublesome matters in that aerodynamic factors and aesthetic factors need to be considered. Recently, as one of alternatives to incorporating such a shark fin antenna into a vehicle, a transparent antenna film has been attracting attention in the market. The transparent antenna film for a vehicle may be provided inside a glass of a vehicle. As an example, the transparent antenna film for a vehicle may be disposed on a front windshield of a vehicle. However, since the front windshield glass of the vehicle is embedded in the vehicle frame made of metal, there is a problem in that the antenna film is disturbed by electric waves from the vehicle frame. In order to minimize such interference of electric waves, it is preferable to space the antenna film from the vehicle frame, but in this case, the length of a portion for supplying power to the antenna film becomes long. When the length of the portion for supplying power to the antenna film becomes long, there is a problem that the signal reception rate of the antenna film is lowered. Therefore, there is a need for developing a technique capable of efficiently arranging the constituent elements while minimizing the interference of electric waves. Disclosure of Invention Problems to be solved by the invention The present invention aims to provide a laminated glass and a method for manufacturing the laminated glass, which can minimize the interference of electric waves to an antenna film arranged in the interior of a vehicle glass and ensure the signal receiving rate of the antenna film. Measures taken to solve the problems In one example, a laminated glass includes a first glass, a second glass disposed at a distance from the first glass in a reference direction and including a first hole penetrating in the reference direction, an antenna disposed between the first glass and the second glass, a circuit board penetrating the first hole and connected to the antenna, and a cover portion bonded on a surface of the first glass on the reference direction side and extending along an edge of the surface of the first glass on the reference direction side, wherein the cover portion is capable of covering the first hole when viewed in the reference direction. In another example, the circuit board further includes a first intermediate layer in contact with the reference direction side of the first glass, and a second intermediate layer in contact with the opposite direction side of the reference direction of the second glass, wherein a second hole communicating with the first hole and having a shape corresponding to the first hole is formed in the second intermediate layer, and the circuit board is capable of penetrating the first hole and the second hole. In still another example, the antenna is disposed on the opposite direction side of the reference direction of the second intermediate layer, and the circuit board includes a first portion having one end connected to the antenna and disposed on the opposite direction side of the reference direction of the second intermediate layer, a second portion extending from the other end of the first portion in the reference direction and penetrating the first hole and the second hole, and a third portion extending from the reference direction side end of the second portion and contacting a surface of the reference direction side of the second glass, a direction from which the first portion extends and a direction from which the third portion extends from the second portion can correspond to each other. In yet another example, the laminated glass further includes a sealing material that fills in the remaining area of the first hole and the second hole except for the area occupied by the circuit board. In yet another example, the antenna is CPWG (Co-Planar Waveguide with Ground, grounded coplanar waveguide) antenna, the circuit board is FPCB (Flexible Printed Circuit Board ) and the length of the circuit board is 20mm to 70mm, and the sealing material may be thermoplastic resin.
