摘要

移动用户的急剧增长、基于物联网的应用以及连接数万亿设备的惊人通道容量需求是前几代移动设备面临的一些巨大挑战,5G成为关键解决方案。虽然5G MIMO可以提高信道容量和频谱效率,但在有限的空间内将多个天线集成到手机中是非常具有挑战性的。因此,本文提出了一种工作在LTE(长期演进)42、43和46频谱(sub-6 GHz频段)的多频段10元阵列天线,用于第四代/第五代(4G/5G)现代手机的MIMO应用。设计了一种简单的t形槽天线,用于获得LTE 42/43和46频段的10元MIMO天线实现。该天线阵列采用低价格的FR-4基板集成,该基板通常用于5.7- 6英寸智能手机,尺寸为150mm × 80mm × 0.8mm。仿真结果表明,在工作频率范围内,端口之间具有良好的阻抗匹配和隔离性(> -12 dB),辐射效率(> 70%)和包络相关系数(ECC< 0.05)。因此,所设计的MIMO天线阵列有效地有利于5G MIMO智能手机提高数据输出和频谱效率。

Dual-Band 10-Element MIMO Array for 5G Smartphones in Sub-6 GHz
The dramatic growth of mobile users, IoT-based applications, and astounding channel capacity requirements to connect trillions of devices are some huge challenges of the previous mobile generations, 5G turned up the key solution. Although the 5G MIMO can boost channel capacity and spectrum efficiency, it is very challenging to integrate multiple antennas into a mobile phone with limited space. Therefore, we presented a multi-band 10-elements array antenna operating at the LTE (long term evolution) 42, 43, and 46 frequency spectrum (sub-6 GHz band) for MIMO applications in fourth/fifth generation (4G/5G) modern mobile phones in this paper. A simple T-shaped slot antenna is designed to acquire 10-element MIMO antenna implementation in LTE 42/43 and 46 bands. The presented antenna array is integrated using a low-priced FR-4 substrate which is typically used for 5.7- 6-inch smartphones and possesses dimensions of 150mm × 80mm × 0.8mm. The simulated results show superb impedance matching and isolation between ports (> -12 dB), radiation efficiency (>70 %), and Envelope Correlation Coefficient (ECC< 0.05) over the operational frequency. Consequently, the designed MIMO antenna array is effectively favorable for the 5G MIMO smartphone to enhance data output and the spectrum efficiency.
