Abstract

This article introduces the design of a multi-coupling feed antenna (MCFA) appropriate for 4G LTE, 5G NR (sub-6 GHz), and WLAN frequency bands. Most antenna designs used in different consumer electronic products only include specific 5G NR frequency bands, while the MCFA antenna proposed in this article covers applications in multiple frequency bands and will meet the needs of more communication devices. MCFA is designed on an FR-4 substrate and uses the coupled-feed structure to achieve diverse operating frequencies. This article also uses the antenna to construct a multi-coupling feed antenna MIMO system (MCFA-MIMO system), which is suitable for electronic devices such as laptops, smartphones, and Wi-Fi base stations. The antenna uses a simple structural design and does not require any RLC components to achieve multiple operating frequency bands, isolation below -11dB, a maximum gain of 4.7, and a maximum efficiency of 78%. The measurement and simulation results of the proposed antennas prove that each multi-band antenna performs consistently in MIMO systems and has high gain and high isolation performance. The simulation values of the specific absorption rate (SAR) of MCFA-MIMO system comply with international specifications and will not harm human health. This makes this antenna design a candidate for modern portable electronic devices.

低SAR多耦合馈源天线和多设备MIMO系统设计：适用于多波段无线通信

本文介绍了一种适用于4G LTE、5G NR （sub-6 GHz）和WLAN频段的多耦合馈电天线（MCFA）的设计。不同消费电子产品中使用的天线设计大多只包括特定的5G NR频段，而本文提出的MCFA天线涵盖了多个频段的应用，将满足更多通信设备的需求。MCFA设计在FR-4基板上，采用耦合馈电结构实现不同的工作频率。本文还利用该天线构建了一个多耦合馈电天线MIMO系统（MCFA-MIMO系统），该系统适用于笔记本电脑、智能手机和Wi-Fi基站等电子设备。该天线采用简单的结构设计，不需要任何RLC元件即可实现多个工作频段，隔离度低于-11dB，最大增益4.7，最大效率78%。测试和仿真结果表明，各多波段天线在MIMO系统中性能一致，具有高增益和高隔离性能。MCFA-MIMO系统的比吸收率（SAR）模拟值符合国际规范，不会对人体健康造成危害。这使得这种天线设计成为现代便携式电子设备的候选天线。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
