有许多不同的方法用于计算直线天线或散射体的复固有频率。最精确的方法是从导线电流积分方程的数值解中得出的。然而，由于获得这种解决方案的相对困难，过去已经开发并使用了这些谐振频率的几种不同近似。最近，Myers等人的一篇论文描述了计算这些谐振频率的变分方法。本文简要介绍了每种用于确定导线谐振的方法，然后比较了直径与长度比（d/L）为0至0.1的导线的每种方法的结果。
There are a number of different methods for computing the complex natural frequencies of a straight wire antenna or scatterer. The most accurate method is that derived from a numerical solution to the integral equation for the wire current. Due to the relative difficulty in obtaining this solution, however, several different approximations to these resonant frequencies have been developed and used in the past. Most recently, a paper by Myers, et al. has described a variational approach for computing these resonant frequencies. This note provides a brief description of each of these methods for determining the wire resonances, and then presents a comparison of the result of each method for a wire of diameter to length ratio (d/L) ranging from 0 to 0.1.
