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...
