有许多不同的方法来计算直线天线或散射器的固有频率。最精确的方法是对导线电流的积分方程进行数值求解。然而，由于获得这种解相对困难，过去已经开发和使用了几种不同的固有频率近似。最近，Meyers的一篇论文描述了一种计算这些固有频率的变分方法。本文简要介绍了测定直导线固有频率的每种方法，然后对直径与长度比（d/L）为0至0.1的导线的每种方法的结果进行了比较。
There are a number of different methods for computing the 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 natural frequencies have been developed and used in the past. Most recently, a paper by Meyers, has described a variational approach for computing these natural frequencies. This paper provides a brief description of each of these methods for determining the natural frequencies of a straight wire, 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.
