四臂螺旋天线研究与设计

Study and Design of the Quadrifilar Qelix Antenna

本文设计了一种多频点角锥形四臂螺旋天线,并对其各种参数进行了优化。天线设计工作在L波段,各频点驻波系数小于2,天线要求为右旋圆极化。利用Ansoft HFSS软件对天线进行了仿真分析,结果表明该天线具有良好的增益特性和方向图特性,基本实现了天线的设计要求。

In this paper, a method for designing a quadrifilar helix antenna is proposed, and the parameters of the antenna are optimized by artificial method. The antenna are designed to ensure VSWR〈2 at around L-band, and fight hand circular polarization. Using the Ansofl HFSS software to optimize the quadrifilar helix Antenna form, on this condition, the simulated results show that the quadrifilar helix antenna proposed in this paper has well gain and directional effect and agrees well with the ideal ones.
