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.

Algorithms and Numerical Techniques for Modern Antenna Measurements in MATLAB is a landmark resource that brings clarity, transparency, and practical utility to one of the most complex and rapidly evolving areas of modern RF engineering. Written by recognised experts Stuart Gregson and Marc Dirix, this book bridges the critical gap between classical electromagnetic theory, antenna metrology, and the computational techniques that underpin today's industrial and research-grade measurement systems.Drawing on decades of hands-on experience in industry, academia, and standards-driven environments, the authors present a comprehensive suite of robust, portable, and fully explained MATLAB® algorithms for processing, interpreting, and validating antenna measurements across planar, cylindrical, and spherical near-field ranges. Each chapter carefully connects mathematical foundations with implementation‑ready code, empowering practitioners not only to use the algorithms but to truly understand them.From coordinate transformations, polarisation handling, and far-field data extraction, to advanced mode expansions, probe compensation, measurement correction, and scattering suppression, this book provides a uniquely complete and practical treatment of the digital backbone of antenna metrology. The included modelling and simulation tools enable engineers to generate reliable verification data, explore measurement scenarios, and build digital twins of antenna ranges - capabilities increasingly essential in an era of automation and robotic measurement systems.Whether you are a postgraduate researcher, antenna engineer, measurement specialist, or developer working with RF systems, Algorithms and Numerical Techniques for Modern Antenna Measurements in MATLAB offers an indispensable reference that demystifies the "black‑box" numerics of antenna measurements and equips you with a powerful, extensible toolkit for modern practice.

This greatly expanded, co-authored, two-volume text provides a comprehensive introduction and explanation of both the theory and practice of modern antenna measurements, from their most basic postulates and assumptions, to the intricate details of their applications in various demanding modern measurement scenarios.Starting with an initial examination of the properties of antennas that allow them to enhance the free-space interaction of electronic systems, the authors then introduce direct far-field and indirect far-field forms of antenna measurements and their various implementations. Detailed descriptions are given of the direct far-field measurement technique CATR (Compact Antenna Test Ranges), Body-Centric measurements, and detailed developments of standard planar, cylindrical, spherical and non-canonical near-field techniques; and includes a through treatment of near-field range error budgets which are an indispensable part of antenna metrology. The books conclude with recent advances in measurement techniques such as aperture diagnostics, phase-less antenna metrology, error correction, and range multi-path suppression techniques. Extensive examples illustrate the concepts and techniques covered.This second edition is thoroughly expanded and now includes new chapters on near-field to far-field transforms from non-canonical surfaces, electromagnetic modelling of CATRs and near-field antenna measurement systems. In addition, there is an expanded chapter on coordinate systems, polarization basis and antenna pattern plotting and new sections on more specialized topics such as 5G and Radome measurements.
