Abstract :
Both platform and wall antennas stirring are known to reduce uncertainty when measuring wireless devices in reverberation chamber (RC). There is a maximum limit on the number of independent platform positions, surpassing which there will be no more improvement in accuracy. The present paper introduces such a limitation on the number of platform positions in a recently published new uncertainty model for the RC.
