Current development of 5G+ networks requires large and steerable phased antenna arrays to overcomepath-loss and to exploit spatial selectivity. Many phased array configurations are capable of achieving therequired wide steering at the expense of a high element count to meet gain requirements. The objective of thiswork is to explore novel phased-array architectures, capable of driving more than 1000 elements with agilityvia real-time calibration to minimize the side lobe levels (SLL) and grating lobe levels (GLL). The proposedapproach aims to break the ULAs into sub-arrays, randomly distributed in order to break periodicity andleading to lower SLL and GLL. Using existing antenna arrays implemented in high-performance packaging(LTCC), this project will target the implementation of the required control algorithm and feed networkscapable of real-time calibration. For each the randomly distributed sub-arrays, the complex weight will becalculated and corrected for the desired steering by properly aligning phase excitation.

当前 5G+ 网络的发展需要大型且可操纵的相控天线阵列来克服路径损耗并利用空间选择性。许多相控阵配置能够实现所需的宽转向，但需要大量元件来满足增益要求。这项工作的目标是探索新颖的相控阵架构，能够通过实时校准灵活地驱动 1000 多个元件，以最小化旁瓣电平 (SLL) 和栅瓣电平 (GLL)。所提出的方法旨在将 ULA 分成随机分布的子阵列，以打破周期性并导致较低的 SLL 和 GLL。该项目将利用高性能封装（LTCC）中现有的天线阵列，实现所需的控制算法和能够实时校准的馈电网络。对于每个随机分布的子阵列，将计算复数权重并通过正确对准相位激励来校正所需的转向。
