ABSTRACT:
A radio-frequency unechoic chamber (electric wave nonreflecting room) is disclosed. The radio-frequency unechoic chamber comprises radiowave reflectors which are provided on all inside of peripheral walls whose upper portion is open and a screen to cut off reflected waves which is arranged between an antenna and the mounting table of a test apparatus and which has a gap for allowing only direct waves from said antenna to pass. The radio-frequency unechoic chamber further may comprise a radiowave reflector which forms a triangular prism together with the floor surface and whose longitudinal direction coincides with the direction connecting the antenna and the mounting table of the test apparatus and which is provided on the floor surface, a radiowave reflector which forms a triangular prism together with the ceiling surface and whose longitudinal direction coincides with the direction connecting the antenna and the mounting table of the test apparatus and which is provided under the ceiling surface, and radiowave absorbers provided under the ceiling surface where said radiowave reflector is not provided.
