The scope of claims for utility model registration and the brief description of the drawings are amended as follows. Scope of claim for Utility Model Registration' An object to be electromagnetically measured is placed in an anechoic chamber, which is hermetically surrounded by a shield panel made of plywood with electrically conductive metal plates on both sides, and whose sides and ceiling are coated with radio wave absorbing material. At the same time, in the structure of the floor on which the measurement angle antenna is set at a predetermined distance from the electromagnetic measurement object, a large number of low dielectric constant sleeves are installed upright on the shield panel, or a filling material is interposed between the sleeves. A hard non-conductive low dielectric constant floor panel is placed and laid on the sliver and the filling, and a wear-resistant waterproof low dielectric constant sheet is laid on the floor panel and above to form a floor. Then, a radio wave absorbing material is buried under the sheet between the position where the electromagnetic object to be measured is placed and the antenna set position, changing the radio wave absorption characteristic from large to small from the former position to the latter position. 1. A floor structure of a radio anechoic chamber, characterized in that it is equipped with radio wave characteristics that match the radio wave characteristics of the earth. Brief explanation of the drawings The drawings are explanatory diagrams of the embodiments of this invention, and Figure 1 is 1.
