De-Embedding Unwanted Radiation from Phased-Array Systems in a Reverberation Chamber

In this work, we analyze for the first time antenna-efficiency measurements of a mm-wave phased-array antenna for smartphone applications by use of the reverberation-chamber-based three-antenna method. We measure the efficiency of the total system (array including an RF beamformer), and we introduce...

Description
Summary:In this work, we analyze for the first time antenna-efficiency measurements of a mm-wave phased-array antenna for smartphone applications by use of the reverberation-chamber-based three-antenna method. We measure the efficiency of the total system (array including an RF beamformer), and we introduce a new method to de-embed radiated emissions by other parts of the system from the efficiency result. We compare the measured result to a simulation model and conclude that the reverberation-chamber approach can yield accurate results when unwanted radiation is properly accounted for.
