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.

目前5G+网络的发展需要大型和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。许多相控阵列配置能够实现所需的宽转向，但要满足增益要求，就需要大量的阵元。本论文的目标是探索一种新型的相控阵结构，能够通过实时校准来灵活地驱动超过1000个单元，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分解为随机分布的子阵列，以打破周期性并导致较低的SLL和GLL。利用现有的高性能封装（LTCC）天线阵列，该项目将针对所需的控制算法和实时校准的馈电网络的实施。对于每个随机分布的子阵列，通过适当地对准相位激励，计算和校正复合权重以获得期望的转向。
