Description

Glass for vehicle and method for producing same Technical Field The present application claims the benefit of priority from korean patent application No. 10-2023-0156499 filed on day 2023, 11 and 13, the entire contents of which are incorporated herein by reference. The present disclosure relates to a glass for a vehicle and a method for manufacturing the same. Background With commercialization of wireless communication services in the interior of a vehicle and the exterior of the vehicle, glass for supporting such services in the vehicle is being developed. For example, ETCS (Electronic Toll Collecting System, electronic toll collection system) as a toll payment system of a vehicle, E-Call (EMERGENCY CALL ) as a traffic accident emergency notification device, GNSS (Global Navigation SATELLITE SYSTEM ) as a global navigation system, radio communication of a portable electronic device of a user, and the like are increasing in demand for easy radio communication to a terminal device provided inside a vehicle. For this reason, a radio wave transmission window needs to be provided in the vehicle glass for radio communication by a terminal device or the like provided in the vehicle. On the other hand, a metal coating for insulating the interior of the vehicle may be provided on the vehicle glass, but if a radio wave transmission window is provided for radio communication of a terminal device or the like, a certain region of the metal coating needs to be removed, and thus a region where heat insulation is impossible occurs in a certain region of the vehicle glass. Accordingly, there is an increasing demand for a glass structure for a vehicle capable of transmitting radio waves for radio communication by a terminal device or the like while improving heat insulating performance. Disclosure of Invention Problems to be solved by the invention The present disclosure has been made to solve the above-described problems, and an object thereof is to provide a glass for a vehicle and a method for manufacturing the same, which can improve the radio communication performance of a terminal device and the like and improve the heat insulating performance. Measures taken to solve the problems The glass for a vehicle according to an embodiment of the present disclosure includes a first glass plate, a second glass plate disposed to face the first glass plate, and a metal layer provided on a face of the first glass plate facing the second glass plate and formed with a pattern transmission part in a partial region such that an electric wave incident through the face is transmitted through the first glass plate to be refracted. The method for manufacturing the glass for the vehicle according to the embodiment of the present disclosure includes a step of cutting coated glass provided with a metal layer, a step of irradiating laser to the cut metal layer of the coated glass to form a pattern transmission part, a step of laminating an adhesive film on the metal layer, and a step of laminating a glass plate on the adhesive film. ADVANTAGEOUS EFFECTS OF INVENTION According to the embodiments of the present disclosure, the radio communication sensitivity of a terminal device or the like provided in a vehicle interior can be improved. According to the embodiments of the present disclosure, since the heat insulating property of the vehicle glass may be improved, the heat insulating blocking property of the vehicle glass may be improved. According to the embodiments of the present disclosure, the heat generation area of the vehicle glass increases, so that the heat generation performance of the vehicle glass may be improved.
