A 10‐element multiple‐input multiple‐output (MIMO) handset antenna array with triple‐band operation in the long‐term evolution band 42 (3400‐3600 MHz), band 43 (3600‐3800 MHz), and band 46 (5150‐5925 MHz) is studied in this article. Acceptable antenna performances are obtained by using polarization and pattern diversity techniques. To assess the multiplexing performances of the handset array in 5G, an 8‐element base station array covering 3.4‐7.1 GHz is presented and studied. An 8 × 10 MIMO system incorporating 8 transmit antennas, propagation scenario and 10 receive antennas is successfully reported, and its multiplexing performances are evaluated. The computed channel capacities in the low and high bands can be as high as 43.3 bps/Hz and 41.6 bps/Hz, which are promising for multi‐gigabit‐per‐second (multi‐Gbps) data transmission in 5G. The effects of user's hand and low MIMO order on the channel capacities are also investigated. Results show the robust performances of the proposed antenna system.
