Title:
GLASS SUBSTRATE, LIQUID CRYSTAL ANTENNA AND HIGH-FREQUENCY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/181707
Kind Code:
A1
Abstract:
Provided is a glass substrate with which it is possible to reduce dielectric loss in high-frequency signals, and which also has excellent thermal shock resistance. This invention satisfies the relation {Young's modulus (GPa) × average thermal expansion coefficient (ppm/°C) at 50-350°C}≤300 (GPa·ppm/°C), wherein the relative dielectric constant at 20°C and 35 GHz does not exceed 10, and the dielectric dissipation factor at 20°C and 35 GHz does not exceed 0.006.
