“…In [6], the author used DGS and via to achieve high isolation but the second band of their antenna is rather narrow for modern wide-band equipment. Others triple-band MIMO antenna researches presented in [7]- [9] can also get low mutual coupling but their total dimensions are relatively large. In consequence, these designs are not easy to ensure high isolation when implemented in compact handheld gadgets.…”

Recently, the Multiple-input multiple-output (MIMO) antennas have been used a lot and attracted many researchers in advanced high-speed wireless communication systems. MIMO antennas are an essential part not only in access points but also in end-user devices. This technology allows a significant increase in channel capacity, but also lead to a challenge of minimize mutual coupling and in the meantime reserved antennas' compact size. In this study, we propose a triple-band MIMO antenna design. By using a symmetric parasitic structure, isolation between radiation elements is significantly improved. Besides, each antenna element is designed using a combination of planar structure and 8 Fibonacci curves that makes it compact in size and easy to fabricate in the circuit board of 5G/ Wi-Fi 6 terminals. With a total dimension of 34.8* 68.2*1.6mm 3 , the proposed MIMO antenna design can operate at three bands of 2.4GHz, 3.5GHz, and 5GHz with wide bandwidths of 11.4%, 9.4%, and 14.58%, respectively. The results are analyzed based on simulation, measurement, and experiment.
