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'.
The utility of the planar methodology is illustrated with example measurement campaigns that include discussion of the characterisation of a wide range of antennas. Advanced techniques including back transforms and poly-planar scan techniques, plus error assessment and correction, are examined and explained along with an extensive review of data assessment methodologies.
A large number of near-field 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 Near-Field Measurement Technique'. All three 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, comprehensive and practical text that will act as a single reference for all aspects of the measurement technique.

'At last, a must-have complete reference source for the foundations, principles and practice of planar near field antenna measurements. The principles are presented in user friendly math from the Maxwellian basis, to the plane wave spectra, to the latest advances. Practical measurement aspects, including sampling, alignment, truncation, positioning errors, polarization and multiple reflections, are examined in detail. This book is a brilliant collection of the body-of-knowledge of planar near field measurement with extensions to the future. I highly recommend this book for antenna measurement practitioners and those new to antenna measurements.' -- Ed Joy, Professor Emeritus, Georgia Institute of Technology
