Abstract
The present invention relates to an apparatus for measuring antenna radiation efficiency, wherein a random field measurement method can be adopted. In this apparatus, a to-be-measured antenna and a standard antenna are situated in a frame. In the frame, a plurality of rods, which are horizontally movable and extend vertically, are supported. A plurality of radio wave scatterers whose intervals and curvatures can be determined at random are held to the rods. In the frame, a random field is created by the radio wave scatterers.
