Book Description
Excerpt from Near-Field Antenna Measurements on a Cylindrical Surface: A Source Scattering-Matrix Formulation This work addresses the problem of measuring the radiating fields of a test antenna by scanning with a probe antenna on an imaginary cylinder surrounding the test antenna. The problem of measuring the receiving characteristics of the test antenna is very closely related, but for the sake of brevity it will be left as an exercise for the reader. Of course, most antennas are reciprocal so once the radiating or transmitting characteristics are determined the receiving properties follow immediately from the reciprocity relationship (15a). As a first step in formulating the cylindrical scanning technique, the EM fields outside an arbitrary test antenna radiating into free space will be expanded in a complete set of cylindrical waves (eigenfunctions or modes). The test antenna and its coordinate system fixed to the test antenna are shown schematically in figure 1. In cylindrical coordinates the point P is designated by (p, in spherical coordinates by (r, o, It has been shown [4] that in cylindrical coordinates the (e, H) fields in free space (in this case outside the radius (a) of the smallest cylinder circumscribing the test antenna) About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
This single volume provides a comprehensive introduction and explanation of both the theory and practice of 'Planar Near-Field Antenna Measurement' from its basic postulates and assumptions, to the intricacies of its deployment in complex and demanding measurement scenarios. To do this the book initially examines the properties of antennas that allow them to enhance the free space interaction of electronic systems and this leads into a full description of the theory of 'Planar Near-Field Scanning'.

Book Description
This book is useful both for those who want to get initial information on the measurement of the antenna parameters, and for specialists directly involved in the experimental determination of the antenna parameters from the results of measuring the amplitude-phase distribution in the near zone of the antennas. Currently, the near-field method is the most common one for antenna measurements. In most books, an academic approach is given to the issue under consideration and it is difficult to use them for the direct organization of measurements. In many others, specific narrow issues are considered that are accessible to understanding only by highly qualified engineers/readers. The purpose of this book is to get rid of the above disadvantages by offering the reader a more accessible exposition and formulas by which appropriate computer programs can be written with minimal effort. The contents of this book allow interested specialists to be not only users of the near-field measuring facilities, but also help in understanding the principles of their work. This book is intended for engineers and specialists whose activities are related to experimental testing of radio characteristics of complex antenna systems, especially near-field measurements, and is also useful as a textbook for senior students in the field of “radioelectronics” and “radiophysics.”
