带有集成耦合器的开放式波导 (OEW) 天线专为相控阵应用而设计。天线由OEW元件、功率分配器/组合器和耦合器（校准网络的一部分）组成。得益于高度集成的设计方法，天线结构紧凑，有效载荷小。测量结果表明，天线的 VSWR ≤ 2 带宽为 33.3 GHz ∼ 39.8 GHz (17.8%)，辐射方向图在整个工作带宽内保持稳定。
An open-ended waveguide (OEW) antenna with integrated coupler is designed for phased array applications. The antenna composes of OEW elements, power splitter / combiner and coupler (a part of the calibration network). Benefit from the highly integration design method, the antenna has compact structure and small payload. The measured results demonstrate that antenna has a VSWR ≤ 2 bandwidth of 33.3 GHz ∼ 39.8 GHz (17.8%) and radiation pattern keeps stable through the operation bandwidth.
