摘要

本文提出了一种适用于下一代无线网络应用的小型六端口毫米波多输入多输出（MIMO）天线。设计了一个带有Sierpinski插槽的矩形贴片作为主辐射体，在六边形衬底上以31ghz的频率在毫米波频谱上谐振。在MIMO系统中嵌入由主反射器和副反射器组成的阵列天线去耦面（ADS）以提高系统的隔离性。所提出的MIMO结构占地面积为13.86 mm × 16 mm，设计在Rogers RT/Duroid 5880衬底上，厚度为0.508 mm。尽管其结构紧凑，所提出的MIMO天线在相邻端口之间提供了令人印象深刻的-35 dB隔离，并且在整个工作频带中获得了令人满意的9.8 dB增益。制作并测试了该设计的原型。测量结果表明，在30.2-31.8 GHz范围内阻抗带宽为-10 dB。所研究的分集参数使系统的包络相关系数（ECC）低于0.18，信道容量损耗（CCL）小于0.1 bits/s/Hz，群延迟在1.2 ns以内。基于这些特性，建议的MIMO天线可能非常适合与毫米波高容量无线网络兼容。

A six-port High Isolation millimeter wave MIMO antenna based on Array-antenna Decoupling Surface for Next-Generation Wireless Networks

This paper presents a compact-sized six-port millimeter wave Multiple-Input Multiple-Output (MIMO) antenna for next generation wireless network applications. A rectangular patch loaded with a Sierpinski slot is designed as a main radiator to resonate at 31 GHz in the millimeter wave spectrum on a hexagonal-shaped substrate. An Array-antenna Decoupling Surface (ADS) consisting of primary and secondary reflectors is embedded to improve the isolation in the MIMO system. The presented MIMO configuration has a footprint of 13.86 mm × 16 mm, designed on Rogers RT/Duroid 5880 substrate with a thickness of 0.508 mm. Despite its compactness, the proposed MIMO antenna provides an impressive isolation of about –35 dB between the adjacent ports and a satisfactory gain of 9.8 dB in the whole band of operation. A prototype of the design is fabricated and tested. The measured results show a –10 dB impedance bandwidth in the range of 30.2–31.8 GHz. The investigated diversity parameters resulted in an Envelope Correlation Coefficient (ECC) below 0.18, Channel Capacity Loss (CCL) less than 0.1 bits/s/Hz, and Group Delay within 1.2 ns. Based on these attributes, the suggested MIMO antenna may be well suited for compatibility with millimeter-wave high-capacity wireless networks.
