Current development of 5G+ networks requires large and steerable phased antenna arrays to overcomex000D
path-loss and to exploit spatial selectivity. Many phased array configurations are capable of achieving thex000D
required wide steering at the expense of a high element count to meet gain requirements. The objective of thisx000D
work is to explore novel phased-array architectures, capable of driving more than 1000 elements with agilityx000D
via real-time calibration to minimize the side lobe levels (SLL) and grating lobe levels (GLL). The proposedx000D
approach aims to break the ULAs into sub-arrays, randomly distributed in order to break periodicity andx000D
leading to lower SLL and GLL. Using existing antenna arrays implemented in high-performance packagingx000D
(LTCC), this project will target the implementation of the required control algorithm and feed networksx000D
capable of real-time calibration. For each the randomly distributed sub-arrays, the complex weight will bex000D
calculated and corrected for the desired steering by properly aligning phase excitation.
