Wide Band Pyramidal Absorber (WPA) is a 80mm high absorber with 100 x 100 mm size. It has a good absorption performance in wide band between 30MHz and 18GHz when combine with 6.3mm Ferrite Tile. Due to this special characteristic, it’s suitable to build a small anechoic chamber to get a bigger space than build with Foam Pyramidal Absorber. Also, it can increase the frequency from 1GHz to 18GHz at a standard Ferrite Tile only anechoic chamber.
