“…The E is the expectation with respect to different channel realisations, I an identity matrix, η the efficiency, SNR the mean signal-to-noise ratio, K the rank of HH H where H is the channel matrix, and H H denotes the Hermitian of matrix H [28][29][30][31]38]. The channel capacity of the proposed array is calculated and indicated in Fig.…”

A miniaturized and closely packed eight element annular ring multiple-input multipleoutput (MIMO) antenna array is designed to operate from the 3 to 6 GHz band for 5G smartphone applications. In MIMO, the orthogonally placed antenna pairs maintain high isolation. The proposed decoupling structures placed between two adjacent antenna pairs improve the isolation. The decoupling structure consists of a rectangular metallic strip with metallic vias that reduces the mutual coupling and excites the additional modes to extend the bandwidth from 3 to 6 GHz. The MIMO structure offers isolation of more than 24 dB, ECC of less than 0.1, TARC of less than 7 dB over the complete operation band, DG of 10 dB, and more than 95% efficiency. The specific absorption rates (SARs) of the antenna placed in the human head and hand models are 0.41 W/kg and 0.66 W/kg, respectively. The performance obtained with the fabricated prototype offers excellent matching with that of the simulated ones.
