Abstract
A protective plate-equipped reflective member includes a reflective member that reflects or re-radiates a radio wave incident thereon; and a protective plate that is installed on a radio wave-incident side of the reflective member, wherein d=α×λ/(1.75×ε) and α is greater than or equal to 1 and less than or equal to 1.25, where a wavelength specified with respect to an operating center frequency f[Hz] is denoted by λ[mm], a plate thickness of the protective plate is denoted by d [mm], a relative permittivity of the protective plate at the operating center frequency f[Hz] is denoted by ε, and a constant is denoted by α.
