摘要

本文提出了一种设计具有非均匀功率分布的 3×5 诺伦矩阵的方法。设计了多个可调相移器，以实现连续波束转向的能力。此外，还将两个功率分配器与 3×5 诺伦矩阵集成在一起，以产生所需的非均匀功率分布，从而降低侧叶电平。为了确定合适的功率分配比，本文深入研究了每个端口的功率比与不同损耗情况以及切比雪夫分布之间的相关性。为了证实我们提出的方法的有效性，我们设计并制造了一个诺伦矩阵实验原型。制造的 3×5 诺伦矩阵原型可提供连续的波束转向，并实现低于 -22 dB 的边音水平。

A tunable 3×5 Nolen matrix for sidelobe-reduced and beamforming applications

A methodology of designing a 3×5 Nolen matrix with non-uniform power distribution is proposed in this paper. Several tunable phase shifters are designed to realize the capability of continuous beam steering. Additionally, two power dividers are integrated with a 3×5 Nolen matrix to produce the desired non-uniform power distribution, thereby reducing the sidelobe levels. In order to establish the appropriate power divider ratios, this paper thoroughly examines the correlation between power ratio at each port and different loss scenarios as well as Chebyshev distribution. An experimental Nolen matrix prototype has been designed and fabricated to confirm the efficacy of our proposed approach. The fabricated 3×5 Nolen matrix prototype offers continuous beam steering and achieves sidelobe levels below −22 dB.
