Dual-Band MIMO Antenna With Compact Self-Decoupled Antenna Pairs for 5G Mobile Applications

In this paper, a dual-band four-element multi-input and multi-output (MIMO) antenna system based on compact self-decoupled antenna pairs is proposed for the fifth-generation (5G) operation in mobile terminals. By sharing one common grounding branch for the two adjacent antenna units, dual-band anten...

description In this paper, a dual-band four-element multi-input and multi-output (MIMO) antenna system based on compact self-decoupled antenna pairs is proposed for the fifth-generation (5G) operation in mobile terminals. By sharing one common grounding branch for the two adjacent antenna units, dual-band antenna pairs with high isolation can be obtained. In particular, the two compact antenna pairs are placed perpendicularly on both sides of the system ground plane. The MIMO antenna system is optimized to operate in both 3.5 GHz (3.4-3.6 GHz) and 4.9 GHz (4.8-5.0 GHz) bands with isolation better than -17.5 dB for the low band and -20 dB for the high band. The proposed dual-band four-antenna MIMO system is fabricated and measured, and a good agreement between the simulation and measurement is obtained. Moreover, the influences of the phantom hand and display panel on the performance of the MIMO antenna system are also studied and discussed.
