摘要
文章介绍了四臂螺旋天线的结构特性和几何尺寸、螺旋模式;设计了一种小型四臂螺旋天线,采用巴伦平衡结构的自相移馈电方式馈电,将螺旋臂印刷在高介电常数陶瓷柱上,减小了天线的体积,通过仿真分析,该种天线具有良好的宽波束和圆极化特性。
This paper introduces quadrifilar helix antenna mounted structure characteristics and geometry size, spiral pattern, designs a small quadrifilar helix antenna mounted, using the Balun balanced structure of the self phase shift feeding supplying, spiral arm printed in high dielectric constant ceramic column, reduces the volume of the antenna, through the simulation analysis, this antenna has wide beam and good circular polarization characteristics.
