| 本文提出了一种新型的螺旋结构的天线，将角锥螺旋与四臂螺旋的结构巧妙的结合起来，并采用了自相移结构及渐进式的平衡馈电，经有限元法对其辐射特性进行分析和实测，结果都说明该种天线在实现宽波束圆极化的同时展宽了频带，且结构简单。 |

| Abstract: |
| A novel structure of spiral antenna is discussed. The conical spiral structure and quadrifilar spiral structure is linked together, and the antenna is dealt with a self-phased structure and a infinit balun. The simulation results shown by the finite method and the measured results prove that the antenna's structure is simple and band is wider while possessing circular hemispherical beam. |
