Abstract: A dual-antenna building block with high isolation is presented for metal-rimmed fifth-generation (5G) smartphones. A coupled-fed loop antenna and a coupledfed slot antenna based on a simple T-slot etched on the ground plane are meticulously designed to form a compact building block. Notably, although the coupledfed loop antenna and the coupled-fed slot antenna share the same aperture, a desirable isolation of >30 dB is exhibited. Afterward, an 8×8 multiple-input multipleoutput (MIMO) system is achieved by integrating four such dual-antenna building blocks. The measured mutual coupling and envelope correlation coefficients (ECCs) of the presented 8×8 MIMO system are <−18.5 dB and <0.02, respectively.

摘要：提出一款应用于第五代金属边框智能手机的高隔离度两天线模块。基于一个蚀刻在地板上的T形缝隙，通过合理地设计一个耦合馈电环天线和一个耦合馈电缝隙天线，实现了一款紧凑的两天线模块。尽管耦合馈电环天线和耦合馈电缝隙天线共口径，两者之间的隔离度高于30 dB。随后，通过集成4个两天线模块，实现了一款8×8多入多出系统。该系统实测互耦和包络相关系数分别小于<−18.5 dB和<0.02。
