摘要

本文介绍了一种四元件定向多输入多输出（MIMO）矩形介质谐振器天线（RDRA），该天线配备了战略性放置的铜反射板，以增强端口隔离。这种设计的目的是在不影响覆盖面积的情况下扩大覆盖范围。拟议的 MIMO 天线采用可生物降解的聚乳酸进行 3D 打印，以确保机械坚固性，然后与基板集成，以防止误安装问题。所提出的设计具有良好的 MIMO 特性，在 | S 11 | ≤-10 dB 时具有 3 GHz 的带宽（4-7 GHz），所有四个 RDRA 的最小辐射增益均为 7 dBi。该天线展示了不同端口的旋转辐射模式，从而能够在特定方向形成波束。天线的波束宽度为 71.2 ˚，覆盖所有方向，没有任何衰减区。所提出的 3D 打印天线具有简易性、强大的多输入多输出（MIMO）特性和无线通信系统的实用性，使其适用于工业、科学和医疗频段的应用。

Four-Element Biodegradable Substrate-Integrated MIMO DRA with Radiation Diversity

This article presents a four-element directional multiple input multiple output (MIMO) rectangular dielectric resonator antenna (RDRA) equipped with strategically placed copper reflector plates to enhance port isolation. This design aims to achieve an extended coverage range without compromising the coverage area. The proposed MIMO antenna is 3D printed using biodegradable polylactic acid to ensure mechanical robustness and then integrated with the substrate to prevent mis-mounting issues. The proposed design exhibits good MIMO characteristics, registering a 3-GHz bandwidth (4–7 GHz) for | S 11 | ≤-10 dB and a minimum radiation gain of 7 dBi for all four RDRAs. The antenna demonstrates a rotation of radiation patterns for different ports, thus enabling beam formation in specific directions. With a beam width of 71.2 ˚ , the antenna covers all directions without any fade zones. The proposed 3D printed antenna offers simplicity, strong MIMO properties, and practicality for wireless communication systems, making it suitable for industrial, scientific, and medical band applications.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
