引言方形螺旋天线就是所说的阿基米德圆形螺旋的对应物。到目前为止,方形螺旋的大部分工作都是实验性的,并且这个天线的设计还只是以电流带理论[1]为基础,可是这一理论只给出了辐射特性的定性分析。本文的主要目的在于,从设计观点对这种形式的天线进行分析。借助计算机来求解Mei的积分方程[2]。给出了电流分布、输入阻抗、辐射方向图和轴比等的数字结果和实 Introduction The square spiral antenna is the counterpart of the Archimedes circular spiral. So far, much of the work on square spirals has been experimental, and the design of this antenna has been based on the current band theory [1], but this theory gives only qualitative analysis of the radiation characteristics. The main purpose of this article is to analyze this form of antenna from a design point of view. Using computer to solve Mei’s integral equation [2]. The digital results and realizations of current distribution, input impedance, radiation pattern and axial ratio are given
