摘要

本研究构建了一个紧凑型耦合馈电双天线构件。该构件结构简单，易于加工，具有很高的隔离度。双天线构件由完全重叠的耦合馈电环形天线和耦合馈电槽形天线组成。基于该双天线模块，设计了一个八元 MIMO 系统，并对制作的八元 MIMO 阵列进行了测量。在不使用任何去耦元件的情况下，所设计的八元件 MIMO 系统的测量隔离度为 18.5 dB。此外，MIMO 阵列具有良好的测量效率，在整个工作频段内的测量效率变化范围为 43%-54%。MIMO 系统的 ECC 测量值为 0.02。因此，所设计的 MIMO 阵列在 5G 金属边框手机应用中具有巨大潜力。

A high-isolation coupled-fed building block for metal-rimmed 5G smartphones

A compact coupled-fed dual-antenna building block has been constructed in this study. The building block is simple in structure and easy to process, and has a high degree of isolation. The dual-antenna building block is composed of a coupled-fed loop antenna and a coupled-fed slot antenna that completely overlap. Based on this dual-antenna module, an eight-element MIMO system is designed, and the fabricated eight-element MIMO array is measured. The measured isolation of the designed eight-element MIMO system is >18.5 dB without any decoupling element. In addition, the MIMO array has good measured efficiencies, with a measured efficiency variation range of 43%–54% in the entire working frequency band. The measured ECC of the MIMO system is <0.02. Therefore, the designed MIMO array has great potential in 5G metal-rimmed mobile phone applications.
