Abstract

This work presents a compact two-element multi-input-multi-output (MIMO) antenna for 5G-enabled IoT devices. The antenna operates over a wide frequency range of 24.6 to 31.4 GHz (28-GHz band) and 57.6 to 60.2 GHz (60-GHz band). Each MIMO element consists of an inverted L-shaped slotted radiator with a partial ground plane. The antenna offers a peak gain of 5.45 and 5.56 dBi across two operating bands. The minimum isolation between the two ports is −26.5 dB, reaching a maximum value of over −45 dB. The investigation of MIMO metrics like “envelope correlation coefficient (ECC),” “diversity gain (DG),” “mean effective gain (MEG),” “channel capacity loss (CCL),” and “total active reflection coefficient (TARC)” also show favorable characteristics. The antenna is fabricated on a 10 × 22 × 0.503 mm³ Rogers 5880 substrate. The experimental results are in close agreement with that of the simulation results. The distinguishing features of the proposed antenna such as its compact design, simple geometrical configuration, wide operating bandwidth, low ECC, and high isolation make it a strong candidate for 5G-enabled IoT devices.

适用于 5G 物联网设备的 28/60-GHz 宽带 MIMO 紧凑型平面天线

摘要这项研究为支持 5G 的物联网设备提出了一种紧凑型双元件多输入多输出 (MIMO) 天线。该天线可在 24.6 至 31.4 GHz（28-GHz 频段）和 57.6 至 60.2 GHz（60-GHz 频段）的宽频率范围内工作。每个 MIMO 元件都由一个带部分接地平面的倒 L 形开槽辐射器组成。该天线在两个工作频段的峰值增益分别为 5.45 和 5.56 dBi。两个端口之间的最小隔离度为-26.5 dB，最大值超过-45 dB。对 "包络相关系数（ECC）"、"分集增益（DG）"、"平均有效增益（MEG）"、"信道容量损失（CCL）"和 "总有源反射系数（TARC）"等 MIMO 指标的研究也显示出良好的特性。天线是在 10 × 22 × 0.503 mm3 的罗杰斯 5880 衬底上制作的。实验结果与仿真结果非常吻合。该天线具有设计紧凑、几何配置简单、工作带宽宽、ECC 低和隔离度高等显著特点，是 5G 物联网设备的理想选择。

期刊介绍： The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues. The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered: -Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.) -System control, network/service management -Network and Internet protocols and standards -Client-server, distributed and Web-based communication systems -Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity -Trials of advanced systems and services; their implementation and evaluation -Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation -Performance evaluation issues and methods.
