Abstract: A novel approach to widening the active reflection coefficient (ARC) bandwidth of an antenna array, employing a parasitic coupling network (PCN), is investigated in this article. Different from traditional tightly coupled arrays adopting space structures for enhancing the coupling in balanced-excitation antennas, a PCN derived from rigorous formulas is employed in the feeding lines of unbalanced-excitation ones. Based on network analysis, the mutual coupling utilization condition for an (M×N)‍-‍element antenna array is initially deduced, and the PCN is implemented. Then, the PCNs are realized by introducing a parasitic element and a coupling network between the two-element H-plane and E-plane dual-layer coupled microstrip antenna arrays, resulting in 10.9% and 30.8% bandwidth enhancements compared with the original arrays, respectively. Moreover, the PCNs are further expanded to multielement antenna arrays, including three- and five-element one-dimensional and 8×2 two-dimensional arrays, exhibiting approximately 40% overlapped ARC bandwidths with normal radiation patterns, steady gains, and applicable scanning characteristics. The results indicate its potential application in large-scale wideband arrays.

摘要：本文研究了一种利用寄生耦合网络（PCN）来拓宽天线阵有源反射系数（ARC）带宽的新方法。与传统紧耦合阵列采用空间结构来增强平衡馈电天线间耦合不同的是，采用严格公式推导的PCN被加载至非平衡馈电天线的馈线中。首先在网络分析的基础上推导了M×N元天线阵的耦合利用条件并实现了PCN。然后，通过在二元H面和E面双层耦合微带天线阵之间引入寄生单元和耦合网络实现了PCN；与原阵列相比，带宽分别提高10.9%和30.8%。此外，PCN被进一步扩展到多元天线阵，包括三元和五元一维阵列以及8×2二维阵列；这3款天线阵都具有40%左右的共用ARC带宽，且有正向辐射方向图、稳定增益和适宜的扫描特性。结果表明PCN在大规模宽带阵列中具有潜在应用前景。
