Abstract

A novel compact quad-band multiple-input-multiple-output antenna (MIMO) with high isolation is presented for universal mobile telecommunications systems (UMTS), wireless local area network (WLAN), and 5G: sub-6 GHz wireless communication applications. The proposed antenna is simulated, fabricated on low cost FR4-epoxy substrate of overall size 25 × 50 × 0.8 mm³. The proposed antenna comprises of two orthogonally placed radiators on top of substrate and ISI-shaped defected ground structure (DGS) on the bottom side. High isolation of above 20 dB is achieved with DGS and orthogonal arrangement of antenna elements. The proposed antenna is fabricated and results are tested. The measured results are well matched with simulated results. The antenna resonates at 1.98 GHz (UTMS), 2.75 GHz (WLAN), 3.37 GHz (5G/n78) and 4 GHz (5G/n77) bands with high gain and radiation efficiency. The simulated and measured results demonstrate that the proposed structure is well suitable for wireless communication applications.

用于 UMTS、WLAN 和 5G Sub-6 GHz 应用的具有缺陷接地结构的多槽四频双元多输入多输出天线

本文介绍了一种具有高隔离度的新型紧凑型四频多输入多输出天线（MIMO），适用于通用移动通信系统（UMTS）、无线局域网（WLAN）和 5G：6 GHz 以下无线通信应用。对所提出的天线进行了仿真，并在总尺寸为 25 × 50 × 0.8 mm3 的低成本 FR4-epoxy 基板上进行了制造。拟议的天线由两个正交放置在基板顶部的辐射器和底部的 ISI 形缺陷接地结构（DGS）组成。DGS 和正交排列的天线元件实现了 20 dB 以上的高隔离度。对提出的天线进行了制造和结果测试。测量结果与模拟结果十分吻合。天线谐振频率为 1.98 GHz（UTMS）、2.75 GHz（WLAN）、3.37 GHz（5G/n78）和 4 GHz（5G/n77），具有较高的增益和辐射效率。模拟和测量结果表明，所提出的结构非常适合无线通信应用。

期刊介绍： The Journal on Mobile Communication and Computing ... Publishes tutorial, survey, and original research papers addressing mobile communications and computing; Investigates theoretical, engineering, and experimental aspects of radio communications, voice, data, images, and multimedia; Explores propagation, system models, speech and image coding, multiple access techniques, protocols, performance evaluation, radio local area networks, and networking and architectures, etc.; 98% of authors who answered a survey reported that they would definitely publish or probably publish in the journal again. Wireless Personal Communications is an archival, peer reviewed, scientific and technical journal addressing mobile communications and computing. It investigates theoretical, engineering, and experimental aspects of radio communications, voice, data, images, and multimedia. A partial list of topics included in the journal is: propagation, system models, speech and image coding, multiple access techniques, protocols performance evaluation, radio local area networks, and networking and architectures. In addition to the above mentioned areas, the journal also accepts papers that deal with interdisciplinary aspects of wireless communications along with: big data and analytics, business and economy, society, and the environment. The journal features five principal types of papers: full technical papers, short papers, technical aspects of policy and standardization, letters offering new research thoughts and experimental ideas, and invited papers on important and emerging topics authored by renowned experts.
