线和环天线广泛用于从低频到超高频的通信系统中，或者以单独元件的形式，或者与其他类似元件一起布置以形成相控阵列。它们也经常被用作探测未知环境的探针，或作为建模更复杂系统和结构的基础。在这一章中，我们将讨论线天线和环形天线作为隔离元件的重要特性。我们的重点将是为一些基本天线形式开发具有足够精度的简单表达式，以便读者可以将其推广到与其特定需求相关的更复杂的复合结构，而无需过多的重新制定和计算。出于这个原因，我们的方法将是从那些计算上更苛刻的方法在文献中报道有很大的不同。读者在后面的课程中认识到我们解决方案过程的物理描述是很重要的，以便从这种方法中充分受益。
Wire and loop antennas are widely used in communication systems from low to ultra-high frequencies, either in the form of individual elements or arranged with other similar elements to form phased arrays. They are also frequently used as probes to sense unknown environments or as bases for modeling more complex systems and structures. In this chapter we shall be concerned with the important properties of wire and loop antennas as isolated elements. Our emphasis will be to develop simple expressions with sufficient accuracy for some basic antenna forms so that readers can generalize them to more complicated, composite structures pertaining to their particular needs without excessive reformulation and computing. For this reason our approach will be substantially different from those computationally more demanding methods reported in the literature. It is important for readers to recognize the physical description of our solution process in the later sessions in order to fully benefit from this approach.
