摘要

本发明提供一种宽带紧凑型赋形阵列天线，包括N个宽带微带天线单元、一个一分N路带状线威尔金森功分网络以及组装载体，采用多层结构设计的N个宽带微带天线单元水平等间距排布组成线阵，一分N路带状线威尔金森功分网络水平摆放并通过同轴转接接头与N个宽带微带天线单元连接用于为线阵实现所需的赋形效果提供相应的激励幅相，该一分N路带状线威尔金森功分网络采用多层转接互连结构设计以缩减三维占用空间和降低设计成本，组装载体位于天线层与馈电网络层之间起支撑作用，本发明通过合理设计天线单元、激励幅相、馈电网络以及互连匹配结构，实现了一种具有频带宽、占用三维空间小、副瓣低、增益高、成本低的优点的宽带紧凑型赋形阵列天线。

英文（機器翻譯）： The invention provides a broadband compact shaped array antenna, which includes N broadband microstrip antenna units, a one-point N-way stripline Wilkinson power division network and an assembly carrier. The antenna units are arranged horizontally and equally spaced to form a linear array, and one sub-N stripline Wilkinson power division network is placed horizontally and connected to N broadband microstrip antenna units through coaxial adapters to realize the linear array. The required shaping effect provides the corresponding excitation amplitude and phase.…
