Abstract

This paper tackles significant challenges in the design of millimeter-wave MIMO (Multi-input Multi-output) antennas for the Ka-band (26-30 GHz) as utilized in 5G applications. Current antenna designs suffer from limitations such as constrained bandwidth, inadequate gain, and restricted beam scanning capabilities, adversely affecting performance, particularly in high-density urban environments. A novel MIMO antenna featuring a 12-port dielectric lens has been proposed to address these issues, introducing several advancements to improve key performance metrics. The antenna demonstrates a peak realized gain of approximately 14 dBi and achieves a bandwidth exceeding 4 GHz. Importantly, it features full 360° beam scanning capabilities and maintains an exceptionally low envelope correlation coefficient (ECC) of less than 0.0014. The design also shows impressive radiation efficiency consistently exceeding 95%, complemented by excellent isolation characteristics with mutual coupling maintained below −30 dB. This research provides a scalable solution that could significantly enhance the performance of next-generation wireless networks, addressing the high demands of urban 5G deployments.

一个紧凑的12端口MIMO介质透镜天线与广角波束扫描的ka波段应用

本文解决了5G应用中用于ka波段（26-30 GHz）的毫米波MIMO（多输入多输出）天线设计中的重大挑战。目前的天线设计受到带宽限制、增益不足和波束扫描能力的限制，对性能产生不利影响，特别是在高密度的城市环境中。为了解决这些问题，提出了一种具有12端口介质透镜的新型MIMO天线，并引入了一些改进以提高关键性能指标。该天线的峰值实现增益约为14 dBi，带宽超过4 GHz。重要的是，它具有完整的360°波束扫描能力，并保持极低的包络相关系数（ECC），小于0.0014。该设计还具有令人印象深刻的辐射效率，始终超过95%，并具有出色的隔离特性，相互耦合保持在−30 dB以下。这项研究提供了一种可扩展的解决方案，可以显著提高下一代无线网络的性能，满足城市5G部署的高要求。
