Field Uniformity Investigation of Reverberation Chamber at Calibration Stage

Field uniformity of our developed reverberation chamber is investigated at calibration stage. The influence of the transmit antenna and the work volume is analyzed and evaluated according to the measurement data. Calibrations with different transmit antenna positions, directions, heights, and dimension of work volume are measured carefully. Field uniformity is analyzed in detail. It is indicated that transmit antenna positions, direction, heights, and dimension of work volume have insignificant influence on the test repeatability of calibrations.
