无线电天线工程

简介:

天线工程已发展成为无线电工程中高度专业的领域,而无线电工程又细分为许多特殊分支。本论文将讨论由电线、桅杆和塔组成的天线,其频率最高可达 30 兆赫。如今,用于更高频率的天线都是工厂设计和制造的,操作和工厂工程师无需再处理设计问题。

在我们感兴趣的范围内,天线方面的经验非常丰富,但不幸的是,关于技术的出版材料相对较少。相比之下,关于天线和辐射理论的文献却非常丰富。本书的目的是试图汇编足够多的有用工程信息,使非专业人士能够处理点对点、地对空和军事通信以及广播中出现的许多普通天线问题。本书包括了一些由甚高频和超高频技术建议的更先进的天线设计,因为随着频谱条件变得更加困难,这些原理即将应用于较低频率。

英文简介:

Antenna engineering has developed into a highly specialized field of radio engineering which in turn is subdivided into many special branches. This treatise will deal with antennas made of wires, masts, and towers for frequencies up to about 30 megacycles. Antennas for higher frequencies are nowadays factory-designed and factory-built, and the operating and plant engineers are relieved of the design problems.

There is a very extensive experience with antennas within our range of interest, but unfortunately there is only a relatively small amount of published material on techniques. In contrast, there is a vast literature on antenna and radiation theory. It is the purpose of this book to attempt to compile a sufficient amount of useful engineering information to enable nonspecialists to handle many of the ordinary antenna problems that arise in point-to-point, ground-to-air, and military communications, and in broadcasting. Some of the more advanced antenna designs suggested by very-high-frequency and ultrahigh- frequency techniques are included because the day is approaching when these principles will have to be applied at the lower frequencies as the spectrum conditions become more difficult.
