DOI: 10.1109/ISIT44484.2020.91739392157-8117http://hdl.handle.net/10230/45342We establish an upper bound on the informationtheoretic capacity of line-of-sight (LOS) multiantenna channels with arbitrary antenna arrangements and identify array structures that, properly configured, can attain at least 96.6% of such capacity at every signal-to-noise ratio (SNR). In the process, we determine how to configure the arrays as a function of the SNR. At low- and high-SNR specifically, the configured arrays revert to simpler structures and become capacity-achieving.application/pdfeng© 2020 IEEE. Personal use of this material is permitted.
