摘　　要：介绍扇面波导宽曲面上连续长槽天线，终端接匹配负载。导出了辐射槽的衰减系数和长槽任意点偏离波导宽面中心线的距离公式，并用于设计Ｘ波段长的连续曲线槽天线，具有满意的性能，如全频带指标等。A continuous long slotted waveguide antenna machined in the curved broad wall of a sectoral waveguide and terminated in a matched load is presented. The coefficient for radiating and the offset from the center line to fhe longitudinal axis of fhe broad wall are deduced and used to design a continuous curved-slot antenna at X-band with a quite satisfactory performance,such as full bandwidth.
