Abstract

In this article, epsilon-negative (ENG) metasurfaces and their application in enhancing antenna performance for 5G applications are presented. A unit cell designed to operate at 26 GHz has been introduced and validated using the 3-D electromagnetic simulator, computer simulation technology (CST). This unit cell is then implemented to construct a metasurface with a circularly polarized radiating patch antenna. Through the analysis of the S-parameters and permittivity of the ENG metasurface, improvements in gain and beamforming capabilities have been realized. A detailed analysis of beamforming capabilities has been performed using the minimum variance distortionless response (MVDR) algorithm. It is shown that the proposed design also enhances the wide-bandwidth capabilities of the antenna by employing a single metasurface layer. Additionally, the design offers a low profile and circular polarization, making it ideal for 5G millimeter-wave systems and multiple input multiple output (MIMO) applications. The results indicate that the ENG metasurface not only boosts antenna efficiency and gain but also enables adaptive beam steering, making it highly suitable for advanced communication systems requiring high data rates and reliable connectivity.

5G天线系统的ENG元表面实现

本文介绍了负epsilon （ENG）元表面及其在5G应用中增强天线性能的应用。介绍了一种工作频率为26ghz的单体电池，并利用三维电磁模拟器、计算机仿真技术（CST）进行了验证。然后实现该单元格以构建具有圆极化辐射贴片天线的超表面。通过对ENG超表面s参数和介电常数的分析，实现了增益和波束形成能力的提高。使用最小方差无失真响应（MVDR）算法对波束形成能力进行了详细分析。结果表明，所提出的设计还通过采用单个超表面层提高了天线的宽带性能。此外，该设计提供了低轮廓和圆偏振，使其成为5G毫米波系统和多输入多输出（MIMO）应用的理想选择。结果表明，ENG超表面不仅可以提高天线效率和增益，还可以实现自适应波束导向，使其非常适合需要高数据速率和可靠连接的先进通信系统。
