摘要
多波束透镜天线因其独特的波束控制机制和优异的宽频带特性,已成为现代无线通信系统的关键组件。系统概述了Rotman透镜与Luneburg透镜两类主流技术的演进历程:从Rotman透镜的平面电路设计原理到Luneburg透镜的球形渐变折射率理论,重点分析了二者在频段适应性、环境鲁棒性及制造工艺方面的差异化特征。进一步揭示了微纳技术的突破性贡献——通过陶瓷3D打印和纳米复合材料实现了透镜结构的轻量化与性能提升。面向6G通信和卫星互联网需求,提出了三大发展方向:基于超表面的智能可重构技术;抗辐射复合材料的空间应用适配;人工智能(AI)辅助的多物理场协同设计方法。
Multi-beam lens antennas,with their unique beam control mechanisms and excellent broadband characteristics,have become key components in modern wireless communication systems.The evolutionary trajectories of two mainstream technologies-Rotman lenses and Luneburg lenses are systematically reviewed,from the planar circuit design principles of Rotman lenses to the spherical gradient-index theory of Luneburg lenses,with a focused analysis of their differentiated features in frequency band adaptability,environmental robustness,and manufacturing processes.The groundbreaking contributions of micro/nano-technology are further highlighted,which has enabled the lightweighting and performance enhancement of lens structures through ceramic 3D printing and nanocomposite materials.In response to the demands of 6G communication and satellite internet,three major development directions:intelligent reconfigurable technology based on metasurfaces,space application adaptability of radiationresistant composite materials,and artificial intelligence(AI)-assisted multi-physics collaborative design methods are proposed.
