Abstract: A shielding box for testing a transmission antenna and a reception antenna includes a first box, a second box, a third box, and an absorption material. The transmission antenna is positioned in the first box. The reception antenna is positioned in the third box. The absorption material is distributed over the inner surfaces of the first box, the second box, and the third box, respectively. The third box is connected through the second box to the first box. The second box provides a relatively narrow connection path for reducing the multipath interference between the transmission antenna and the reception antenna.
