旋转布阵双臂短螺旋天线阵的矩量法分析

内容简介：从混合位方程出发,采用曲线分段的矩量法和脉冲检验基函数分析无限大导电平面上的双臂圆柱短螺旋天线阵列辐射特性。通过推导阵列布阵方式与远区场轴比的关系,介绍一种优化阵列轴比的布阵方法。矩量法的分析结果表明,采用这样的布阵方式实现了很好的轴比特性。计算结果与实验结果吻合较好。

Abstract：This paper presents the analysis of radiation charactenstics ot a bifilar helix array on me infinite conuucnng plane using mixed potential integral equation, and the equation is solved by the moment method incorporating with curved piecewise triangle sub-domain basis and pulse testing functions. With the derivation of the relationship between array and axi- al ratio, a method for the optimization of axial ratio is given. The analysis proved that it can achieve good circular polariza-tion. The results of this paper＇s analysis is closed to the measured results.
