提出了一种基于扩展谐振技术的相控阵设计新电路。扩展谐振是一种功率分配结构，允许构建低复杂性和成本的相控阵。研究了相控阵相邻节点之间可实现的相移，并研究了最大化扫描角的新电路结构。此外，还提出了一种用于设计具有大量天线的发射相控阵的模块化方法。作为原理证明，我们展示了扫描角约为 60 度的 2 GHz 七元发射相控阵。
A new circuit for designing phased arrays based on the extended resonance technique is proposed. Extended resonance is a power dividing structure that allows construction of low complexity and cost phased arrays. Achievable phase shift between adjacent nodes of the phased array is studied and a new circuit structure to maximize the scan angle is investigated. Furthermore a modular approach for designing transmit phased arrays with large number of antennas is proposed. As a proof of principle, a 2 GHz seven-element transmit phased array with a scan angle of approximately 60 degrees has been demonstrated.
