Indoor Channel Capacity Evaluation Utilizing ULA and URA Antennas in the Millimeter Wave Band

This paper studies the capacity of an indoor wireless system operating at the millimeter wave band of 60 GHz using a physical channel model that incorporates smart antennas comprised by multiple elements at both antenna terminals. Two different antenna configurations were realized comprising of uniform rectangular arrays (URAs) and uniform linear arrays (ULAs). The results showed that the system capacity increases significantly if MIMO configuration is utilized instead of the basic SISO channel. The average capacity was found 5.7 b/s/Hz, for the 90% of the cases in URA scenarios, and 3.9 b/s/Hz in ULA cases. Finally, very high data rates, even higher than 1 Gb/s, can be achieved with 64times64 MIMO antenna element arrangement maintaining low SNR.
