国外经典的天线设计教材 I wrote this book from my perspective as a designer in industry, primarily for other designers and users of antennas. On occasion I have prepared and taught antenna courses, for which I developed a systematic approach to the subject. For the last decade I have edited the “Antenna Designer’s Notebook” column in the IEEE antenna magazine. This expanded edition adds a combination of my own design notebook and the many other ideas provided to me by others, leading to this collection of ideas that I think designers should know. The book contains a systematic approach to the subject. Every author would like to be read from front to back, but my own career assignments would have caused to me to jump around in this book. Nevertheless, Chapter 1 covers those topics that every user and designer should know. Because I deal with complete antenna design, which includes mounting the antenna, included are the effects of nearby structures and how they can be used to enhance the response. We all study ideal antennas floating in free space to help us understand the basics, but the real world is a little different. Instead of drawing single line graphs of common relationships between two parameters, I generated scales for calculations that I perform over and over. I did not supply a set of computer programs because I seldom use collections supplied by others, and younger engineers find my programs quaint, as each generation learns a different computer language. You’ll learn by writing your own. IEEE Antennas and Propagation Society’s digital archive of all material published from 1952 to 2000 has changed our approach to research. I have not included extensive bibliographies, because I believe that it is no longer necessary. The search engine of the archive can supply an exhaustive list. I referred only to papers that I found particularly helpful. Complete sets of the transactions are available in libraries, whereas the wealth of information in the archive from conferences was not. I have started mining this information, which contains many useful design ideas, and have incorporated some of them in this book. In this field, 40-year-old publications are still useful and we should not reinvent methods. Many clever ideas from industry are usually published
