报告摘要

This talk is about innovative MIMO OTA Measurement method for large object under test with relatively small integrated wireless system on the objects, such as wireless system in automobile, satellite appliances.  The large object under test generally face eccentrical challenges, in which antennas of the wireless systems are not be able to be positioned in the center of the turn table. The challenges and solutions for this eccentrical OTA measurements are presented in the talk.

The fundamentals of the OTA measurement and international standards for MIMO OTA are discussed with emphasizes on measurement accuracy and complexity of the measurement systems. A real measurement system for large object under test is demonstrated.
