Indoor antenna ranges must have the walls, floor and ceiling treated with RF absorber. The normal incidence performance of the absorber is usually provided by the manufacturers of the materials, however, the bi-static or off angle performance must also be known. In reference [1], a polynomial approximation was introduced that gave a prediction of the reflected energy from pyramidal absorber. In this paper, the approximations are used to predict the quiet zone (QZ) performance an anechoic chambers. These predictions are compared with full wave analysis performed in CST Suite. The results show that the polynomial approximations can be used to give a fairly accurate prediction of the QZ performance of anechoic chambers.
