[Arthur D Yaghjian; Institute for Basic Standards (U.S.). Electromagnetics Division.; United States. National Bureau of Standards.]. Since Far-field, Near-field, Gain and Polarization ratios can be found from the cylindrical mode coefficients, determining for a given antenna is the goal of the near-field measurements.

Near-field vs Far-field Any antenna can be successfully measured on either a near-field or far-field range, with appropriate In Dan Slater wrote a comprehensive book titled "Near-Field Antenna Measurements" about the a cylindrical surface is described around the antenna.

The subject of antenna measurements is one which has undergone revolutionary changes in recent years, in particular within space applications, where high demands are placed upon antenna design and construction. This book represents the specific measurement technique known as the spherical near-field method.

The theoretical treatment of the method is detailed but of sufficient generality to 5/5(2). by Clive Parini, Stuart Gregson, John McCormick and Daniël Janse van Rensburg.

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.

Planar near-field range. Planar near-field measurements are conducted by scanning a small probe antenna over a planar surface. These measurements are then transformed to the far-field by use of a Fourier transform, or more specifically by applying a method known as stationary phase to the Laplace dentalimplantsverobeach.com basic types of planar scans exist in near field measurements.

The theory for probe-corrected measurement of antennas by scanning on a circular cylindrical surface enclosing the test antenna in the near-field is formulated from a source scattering matrix.

A near-field measurement technique for the prediction of asymptotic far-field antenna patterns from data obtained from a modified cylindrical or plane-polar near-field measurement system is presented.
