摘　　要：介绍了一种复合加栽的背腔式平面螺旋天线。通过宽带天线加载减小传输段长度，锯齿加载增加螺旋曲线辐射段有效长度，降低腔体高度等方法，对背腔式平面螺旋天线各参数进行综合优化设计，实现了一种小型化、宽频带、复合加载平面螺旋天线。测量结果显示天线在带宽为5：1频率范围内保持了良好的辐射特性。In this paper, a novel design method of a cavity-backed spiral antenna is proposed and demonstrated, which operates a compact size by reducing the transmission length of spiral cures ,serrated spiral curves to increase the effective radiation length ,reducing the height of the cavity ,as well as the design parameters of cavity-backed spiral antenna are comprehensive optimized, implementation of a compact ,broadband, combined loading planar spiral antenna. Test result shows that antenna present good radiation character.
