Broadband MIMO Antenna with Defective Ground Structure for Mobile 5G Applications
In this paper, a broadband MIMO antenna for 5G applications is proposed with four elements placed orthogonally. The specific dimension of the antenna is 70 × 70 × 2.5 mm3. S-shaped coupling unit are introduced between neighboring components and eight rectangular slots are etched on the ground plane to enhance isolation. Simulation results show that the -6 dB impedance bandwidth is 3.28-5.08 GHz, which is able to cover the N77/N78/N79 bands of 5G and suitable for 5G MIMO mobile devices. The designed four-element MIMO antenna has the advantages of low profile, small size and wide bandwidth, which provides a design idea for the 5G MIMO antenna on the back cover of mobile devices.
