摘要
该文设计了由基片集成波导共腔罗特曼透镜馈电的毫米波十字扫描多波束阵列天线.核心在于提出一种针对罗特曼透镜的共腔设计拓扑结构.这一拓扑结构主要由两组子网络正交放置组合形成，并且两组子网络共享罗特曼透镜的腔体.这一共腔罗特曼透镜可在两个维度同时实现电磁波相位和幅度的控制，与辐射结构连接后可用于产生十字扫描多波束.与传统设计相比，该方法可以降低馈电网络的设计复杂度和提高设计集成度.
Abstract
A shared-cavity Rotman lens for cruciform multibeam array antennas is realized using substrate integrated wave-guide technology. The core of this design is a shared-cavity topology to design a Rotman lens
which is realized by orthogonally combining two sub networks. Thus
these two sub networks can share the common lens cavity. Such a shared-cavity Rotman lens allows for phase and amplitude manipulations in orthogonal dimensions and is capable of generating cruciform scans after connecting to the radiation portion. Compared with traditional designs
such method can significantly reduce the design complexity and improve the integration.
