This expanded and updated second edition with full colour images
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. 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. The second edition
brings the text right up to date. Advanced techniques including
non-canonical transforms, scattering suppression techniques,
equivalent current based diagnostics, extrapolation range
measurements, use of multi-axis industrial robots and UAV drones
for data acquisition are now included, together with a greatly
expanded treatment of uncertainty analysis and planar range
assessment. 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. Principles of Planar Near-Field Antenna Measurements,
2nd Edition is aimed at electromagnetics students, researchers and
professionals, especially those concerned with electromagnetics
metrology.
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.

This book 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.
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
