双臂圆锥对数螺旋天线的研究

Research on Two Arms Conical Log Spiral Antenna

本文利用曲线段三角基展开，伽略金法检验的短量法对一种非叛变天线──双臂圆锥对数螺旋天线进行了分析通过曲线段拟合天线结构以及利用阻抗矩阵的中心对称性减少计算量使得计数精度、速度大为提高。本文的方法和程序也适用于平面螺旋和圆柱螺旋天线的设计和计算文中同时给出大量曲线数据，并将计算结果与文献和实验进行对比。

A new kind of moent method using curved wire segments is used in this paper to analyze a kind of frequency independent antenna-two arms conical log spiral antenna. By using the curved wire Segments to represent the antenna'sstructure and the properties of the central symmetric matrix, the calculation time is much reducecl and the accuracy and speedis enhanced. This program is also suitable to plane spira and conical spiral antennas. This paper also presents a lot of data andcurves and they are verified by the references and experiments. Their results matched fairly well.
