| abstract | A radio anechoic box (1) includes a determined antenna (3) and a determining antenna (4). A distance dimension (L) between the determined antenna (3) and the determining antenna (4) is set, based on an aperture dimension (D) of the determined antenna (3), an aperture dimension (d) of the determining antenna (4) and the wavelength (λ) of a determination frequency, to a value within a range from (D+d)<SP>2</SP>/2λ To 2(D+d)<SP>2</SP>/λ Inclusive. This allows the antenna characteristic of the determined antenna (3) to be determined in the Fresnel region to which the distance dimension (L) is close, similarly to the Fraunhofer region from which the distance dimension (L) is far. |
