天线阵列和多天线系统在超5G无线网络中至关重要，用于提供无线连接，特别是在万物互联的背景下。为了满足这一要求，波束成形技术正在成为自适应按需无线覆盖的关键解决方案。尽管数字波束成形是自适应无线覆盖的主要选择，但一组应用依赖于纯模拟波束成形方法，例如，在点对多点和物理层安全通信链路中。在这项工作中，我们提出了一种新的可扩展的模拟波束成形硬件架构，能够自适应2.5维波束转向和波束成形，以满足覆盖范围的要求。波束形成器硬件包括有限尺寸的麦克斯韦鱼眼透镜，其用作半圆形阵列天线的可缩放馈送网络解决方案。这种独特的硬件架构实现了使用2至8个天线元件的灵活性。波束形成器的发展阶段，而实验波束转向和波束成形的结果显示出良好的协议与估计的性能。
Antenna arrays and multi-antenna systems are essential in beyond 5G wireless networks for providing wireless connectivity, especially in the context of Internet-of-Everything. To facilitate this requirement, beamforming technology is emerging as a key enabling solution for adaptive on-demand wireless coverage. Despite digital beamforming being the primary choice for adaptive wireless coverage, a set of applications rely on pure analogue beamforming approaches, e.g., in point-to-multi point and physical-layer secure communication links. In this work, we present a novel scalable analogue beamforming hardware architecture that is capable of adaptive 2.5-dimensional beam steering and beam shaping to fulfil the coverage requirements. Beamformer hardware comprises of a finite size Maxwell fisheye lens used as a scalable feed network solution for a semi-circular array of monopole antennas. This unique hardware architecture enables a flexibility of using 2 to 8 antenna elements. Beamformer development stages are presented while experimental beam steering and beam shaping results show good agreement with the estimated performance.
