Recent NMI Advances on AESA and MIMO OTA Performance and Conformance Testing Using Reverberation Chamber

With the industrial adoption of complex new radio signals and multi-antenna technologies in emerging wireless systems, several worldwide industries, research communities and standards bodies are now facing new measurement challenges regarding testing to verify that products meet the intended performance parameters demanded by diverse technological requirements. The scope of this talk is to present the recent technical trends and advances in measurement techniques adopted for use in the development of emerging wireless technologies and in standards development activities. Examples of measurement capabilities at the UK National Physical Laboratory (NPL), established under several UK and EU programmes, will be presented. The topics covered include performance and conformance testing of new radio MIMO OTA, and mm-wave hybrid beamformers with large-scale phased arrays using a reverberation chamber.
