平面等角螺旋天线的理论分析与数值仿真

Theoretical Analysis and Numerical Simulation of the Equangular Spiral Antennas

在对平面等角螺旋天线进行理论分析的基础上,采用基于矩量法的电磁场数值仿真软件,研究了平面等角螺旋天线的结构参数对天线辐射场分布的影响以及辐射场分布与解析结果间的差异,给出了一定带宽及工作模式条件下的等角螺旋天线的参数选择方法。

Based on the theoretical analysis of equangular spiral antenna, the electromagnetic field numerical simulation software based on the method of moments is used to study the impacts of structure parameters of equangular sprial antenna upon the antenna radiation field distribution as well as the differences between the radiation field distribution and the analysis results. Also, this paper suggests the parameter selection method of the equangular spiral antenna in a certain bandwidth and under the conditions of working modes.
