Abstract In this paper, we employ a 4‐port Agilent PNA‐X network analyzer with the expansion modules to measure a 2 × 2 multi‐input multi‐output (MIMO) propagation channel at 57–64 GHz frequency band. Moreover, we investigate on the beamforming capabilities of the millimetre‐wave (MMW) MIMO system. For both aforementioned architectures, that is, regular MMW MIMO and MMW MIMO with beamforming, the Shanon capacity criterion is used to evaluate the performance in terms of data transmission rate. The results reveal that we have a remarkable data rate gain due to MIMO transmission and even more when this MIMO is equipped with beamforming capabilities. Copyright © 2014 John Wiley & Sons, Ltd.
