摘　　要：讨论了一种新颖的直线阵──非对称单脊波导共线缝隙阵，用它作垂直线阵元组成平面阵后，能大大压缩波导宽边尺寸，从而实现方位面内大角度扫描，并确保不会出现栅瓣。文中阐述了设计理论和方法，导出了设计公式和曲线，给出了设计步骤和实例。本文对扫描角大于±６０°的平面缝隙相控阵的设计有重要的参考价值。A novel linear array radiating element for use in wide -angle scanned planar slot array is discussed ,It is constituted by asymmetric single ridge waveguides with broadwall shunt collinear slots. The planar array consists of many aforementioned linear array vertical elements can compress greatly the size of waveguide broadwall and realize successfully wide-angle scanning without grating lobes in azimuth.Thedesign theory and method are described ,the design formulas and curves are derived ,and the designprocedures and example for this collinesr slot array is given It is very useful for the design of wide-angle(≥±60°) scanned planar slot phased array.
