Abstract

In this paper, the original open-slot antenna is presented as antenna array elements which yields high isolation between adjacent input ports for future 5G smartphones. Eight novel antenna array elements are designed for the multi-input multioutput (MIMO) array operating in the 3.5 GHz band (3.3–3.7 GHz). Preferable polarization diversity is effectuated by prudently positioning those elements which further reduces the coupling between antenna elements. Good impedance matching (return loss > 10 dB), high isolation (>17.5 dB), high total efficiency (>60%), and low envelope correlation coefficient (ECC, <0.05) were measured across the desired operation bandwidth. Typical results such as S-parameters, radiation efficiency, antenna gain, radiation pattern, and ECCs are to be measured, and they can meet the requirements of MIMO systems. Therefore, the proposed multi-antenna module is promising for future multi-mode smartphone application.
