  • Theory and Practice of Modern Antenna Range Measurements
  • This single volume provides a comprehensive introduction and explanation of both the theory and practice of all forms of modern antenna measurements, from their most basic postulates and assumptions to the intricate details of their application in various demanding modern measurement scenarios. Theory And Practice Of Modern Antenna Range Measurements begins with an initial examination of the properties of antennas that allow them to enhance the free space interaction of electronic systems, followed by an introduction to direct far-field measurements. The text presents a comprehensive treatment of Compact Antenna Test Ranges, Body-Centric measurements, and detailed developments of standard planar, cylindrical and spherical near-field techniques. Detailed discussions are also provided on near-field range error budgets which are an indispensable part of antenna metrology. The book concludes with some of the most recent advances in the various measurement techniques including aperture diagnostics, phase-less antenna metrology, error correction, range multi-path suppression techniques, and gain measurements. Extensive examples illustrate the concepts and techniques. A large number of antenna test facilities exist worldwide but to the authors' knowledge no single text provides a clear step-by-step description of all the details of the Planar, Cylindrical, Spherical Near-Field, Compact Range and Body-centric Measurement Techniques. All four authors have spent a significant proportion of their professional careers involved with antenna measurements and the aim of this text is to provide the reader with a complete, coherent, comprehensive and practical text that will act as a single reference for all aspects of modern antenna measurements.

  • EMI Troubleshooting Cookbook for Product Designers
  • EMI Troubleshooting Cookbook for Product Designers provides the 'recipe' for identifying why products fail to meet EMI/EMC regulatory standards. It also outlines techniques for tracking the noise source, and discovering the coupling mechanism, that is causing the undesired effects. This title gives examples of simple, easilyimplemented, and inexpensive troubleshooting tools that can be built by the engineer or technician, and uses methods that require only a basic understanding of electromagnetic theory and a minimal background in EMI/EMC. It will show the engineer and technician how to develop a process for troubleshooting using a straightforward approach in solving what may seem like a rather complicated problem at first. It will provide guidelines on how to approach an EMI failure, things to try, how to choose the right parts and balance cost, performance, and schedule. This book tells readers trying to solve EMI problems what to do and how to do it.
