摘要

本文介绍了双端口印刷散热器的布局和检查，该散热器的端口之间有一个元表面（MS）吸收壁，在设计的散热器上有一个悬挂的MS。所设计的印刷型多输入多输出（MIMO）辐射器具有以下独特特点：(i) 端口之间的吸波墙可将间距较近的天线之间的分离水平提高 25 dB；(ii) 由双负超材料单元构成的悬浮 MS 增加了两个重要特性，即高增益（高达 8.0 dBi）和在工作频率范围内将线性波转换为圆极化波（5.31-5.65 GHz）。实验结果与优化的模拟结果一致。计划中的天线可在 5.2 和 5.95 GHz 之间有效工作，间隔超过 25 dB。对多输入多输出（MIMO）参数和稳定辐射特性的良好评估证实了它适用于基于 6.0 GHz 以下频率的 5G 通信系统。

Two-Port Circularly Polarized Printed Radiator With High Gain and Isolation Features for Sub-6 GHz 5G Applications

This article explains the layout and examination of two-port printed radiator with a metasurface (MS) absorber wall in between the port and a suspended MS over the designed radiator. The unique characteristics of designed printed multi-input multi-output (MIMO) radiator are as follows: (i) Absorbing wall in between the port advances the separation level among the closely spaced antennas by 25 dB and (ii) suspended MS made up with double negative metamaterial unit cell, which adds two important features, that is, high gain (up to 8.0 dBi) and converts the linear wave into the circularly polarized waves (5.31–5.65 GHz) in between working frequency range. Experimental outcomes have decent promise with optimized simulated findings. The planned aerial works effectively in between 5.2 and 5.95 GHz with above 25 dB separation. Decent assessment of MIMO parameter and stable radiation features confirms its applicability for sub-6.0 GHz-based 5G communication system.

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.
