摘要
利用法向模螺旋的基本原理,推导出获得圆极化法向模螺旋应满足的条件,并对多臂法向模螺旋的波束调控进行了理论分析,获得了从法向到轴向方向之间任意辐射波束的多臂法向模螺旋的设计方法,利用此方法设计了波束倾斜15о的四臂螺旋天线,实测结果达到设计要求。
Based on the basic principle of normal mode helix antenna, the qualification of circular polarized normal helix is educed firstly. Then through the analysis of multiple-arm normal mode helix beam control, its design method is got,and an example of four-arm helix antenna with 15°beam-tilt is designed .Test results show that it can satisfy design requirements.
