VEHICLE WINDOW GLASS

WIPO Patent Application WO/2023/127676

A1

The purpose of the present invention is to improve appearance and ensure antenna characteristics.　This vehicle window glass comprises a glass plate, a light-shielding layer formed on the glass plate, and a planar antenna in which a hollowed-out portion including at least one hole is formed in a planar conductor, wherein where in a plan view of the glass plate, a region having the light-shielding layer is defined as a light-shielding region, and a region having no light-shielding layer is defined as a transmission region, the planar antenna is arranged across the boundary of the light-shielding region and the transmission region and has a first conductor portion that overlaps with the light-shielding region and a second conductor portion that overlaps with the transmission region, and where an area where the planar antenna overlaps with the light-shielding region is defined as a first overlapping area, an area where the planar antenna overlaps with the transmission region is defined as a second overlapping area, the ratio of the area of the first conductor portion to the first overlapping area is defined as a first conductor density, and the ratio of the area of the second conductor portion to the second overlapping area is defined as a second conductor density, the second conductor density is smaller than the first conductor density.
