Title:
ANTI-REFLECTIVE MATERIAL AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/006186
Kind Code:
A1
Abstract:
Provided is a technology for improving the radio wave transmissivity of a dielectric member that reflects radio waves without requiring a design change of the dielectric member itself. An anti-reflective material is provided which reduces the reflection of radio waves and is used by being laminated on a dielectric member that reflects the radio waves. The dielectric member includes a base layer and a coating layer laminated on the base layer. The thickness TYB of the base layer is 1.2 mm to 3.5 mm. The relative permittivity εYC of the coating layer is 3.0 or more. The thickness TX of the anti-reflective material is 10 mm or less. The relative permittivity εX of the anti-reflective material is 2.0 to 7.0.
