I found some aspects of the text, especially chapters 6, 13 and 14, to be problematic. I thought the approach to the exposition of the theory of a given topic to be somewhat choppy. Much text is devoted to finding simplified expressions which can be distracting and impedes understanding. In a few instances, the reader is directed to external sources to get foundational details. And, often, the result presented applies only in special cases, such as, in the far field, or for electrically small antennas, or for antennas an odd integer multiple of a half wavelength. For example, in the section on self-impedance of a thin linear antenna (13-5), the statement is made that it is "common practice to shorten the antenna a few percent to make X11=0." Yet the expression presented for X11 is the sine integral which is non-zero everywhere except at Si(0). So, absent thorough exposition of the theory, this is not helpful to those interested in the general case.

I believe this book would be vastly improved if a systematic approach, in the context of electromagnetic theory, is adopted for exposition of the material. Development of new topics should begin with first principles. Sections building on earlier sections should include appropriate back references. References to external papers or earlier editions should not be used as substitute for exposition of details as these sources are generally inaccessible to the reader. Recognizing the accessibility of powerful mathematics software, much of the material dealing with simplifying assumptions could be edited out in favor of more complete exposition of the theory.

We had this as a reference book for a course in Microwave engineering and was used in a design problem. This is not your leisure book that you can just browse! You have to have advanced calculus/electromagnetism background to understand the concepts.

The book covers all the basic antennae theory and types to topics ranging to radar design.

This is a must have for any RF design engineer.

Since most of the RF jobs in US are with defense and companies like Lockheed Martin and you have to be US citizen to get such jobs, I had to opt for computer networks for graduate studies in US, otherwise I'd have ended up as a RF designer myself.

I found this book to be very helpful and to the point on mostof the material. I thought the math, when given, was quitestraightforward, and the author was sure to explain the actual meaning of the math in quick to understand terms. I have only had this book for two days, and have already been able to walk away with a good bit of knowledge END
