Dual-Band Dual-Fed 5G MIMO Antenna with Multi-Feed Technology

In this paper, a dual-band dual-fed MIMO antenna with good return loss and pretty high isolation is proposed. By manipulating the distance between the shorting pins and the feeding ports, very good antenna array performance can be obtained. The -6dB impedance bandwidth can cover both frequency band N41 and N42 (2496-2690MHz and 3.4-3.6GHz), and the isolation between two feeding ports is better than 14dB. The evolution of the antenna and the simulation results will be introduced in detail. This antenna have a great potential for application in mobile terminal industrial products.
