A quadruple band with L-slotted multiple-input-multiple-output (MIMO) square dielectric resonator antenna (SDRA) for fifth generation (5G) applications at the sub-6 GHz band is presented, which can cover 5G new radio band N77 (3.3–4.2) GHz and N79 (4.4–5) GHz. The proposed structure consists of a single SDRA mounted on a substrate excited by an aperture slot underneath dielectric resonators (DR)s. The performance of SDRA is improved by introducing L-shaped slot on the central part of DRA. Results show that the MIMO SDRA antenna achieves S11<-10 dB and S21<=-15 dB for all resonant frequencies at 3.5 GHz, 4 GHz, 4.6 GHz, and 5 GHz, indicating good performance of the antenna at the desired frequencies. The maximum realized gain is 5.61 dB and 5.01 dB at port 1, 4 GHz and port 2, 4.6 GHz, respectively. The radiation efficiencies are acceptable for all resonant frequencies. Moreover, the proposed antenna design achieved good envelop correlation coefficient (ECC) and diversity gain
