Antireflection material and use thereof

Abstract

Provided is a technique for improving the radio wave transmission of a dielectric member, which reflects radio waves, without requiring a design change of the dielectric member itself. Provided is an antireflection material that is used by being laminated on a dielectric member, which reflects radio waves, to reduce the reflection of the radio waves. The dielectric member includes a base layer and a coating layer laminated on the base layer. The base layer has a thickness TYB of 1.2 mm or more and 3.5 mm or less. The coating layer has a relative permittivity εYC of 3.0 or higher. The antireflection material has a thickness TX of 10 mm or less. The antireflection material has a relative permittivity εX of 2.0 or more and 7.0 or less.
