Abstract: An anechoic antenna chamber includes: a holder on which a device under test (DUT) is configured to be mounted, at least one first antenna configured to radiate a first test signal of a first frequency band, a second antenna provided at an inner side of the antenna chamber and configured to radiate a second test signal of a second frequency, at least one driver configured to rotate the DUT, and a control circuit operatively connected with the at least one first antenna, the second antenna, and the at least one driving part. The control circuit is configured to control the driver to rotate the DUT and control the at least one first antenna to radiate the first test signal having an intensity of a specified range and control the second antenna to radiate the second test signal, while rotating the DUT.
