Title:
HEAT-RAY REFLECTING SUBSTRATE AND WINDOW GLASS
Document Type and Number:
WIPO Patent Application WO/2023/228715
Kind Code:
A1
Abstract:
A heat-ray reflecting substrate (10) comprises a dielectric substrate (11) and a heat-ray reflecting film (13) on at least one principal surface of the dielectric substrate. The heat-ray reflecting substrate includes a radio wave transmissive region (A) in at least a section on the at least one principal surface in plan view. The radio wave transmissive region (A) includes a first repetitive pattern (15) that is formed by a slit section (14) in which no heat-ray reflecting film is present. The first repetitive pattern (15) includes at least two first unit patterns (151a, 151b) that extend along a first axial direction. Each of the first unit patterns (151a, 151b) includes: a first line section (154a, 154b) that extends in the first axial direction; and a first connection section (155a, 155b) having a prescribed configuration.
