Journal ArticleDOI
Basic theory of probe-compensated near-field measurements
TL;DR: In this article, the application of the Lorentz reciprocity theorem to the problem of determining antenna characteristics, including the far-field pattern, is presented and the data required to correct for the directional effects of the probe, the effect of probe correction on the measured data, and the attendant mathematical computations in rectangular systems are described.
Journal ArticleDOI
Spatial sampling and filtering in near-field measurements
TL;DR: In this paper, a sample spacing criterion and a data minimization technique for measurements made over the surface of a plane in the near field of an antenna are presented and compared with those measured on a standard far-field range.
Journal ArticleDOI
Applications of probe-compensated near-field measurements
E. Joy,W. Leach,G. Rodrigue +2 more
TL;DR: In this paper, the theory of near-field measurements for antenna practitioners is summarized, and the measurement procedures in three coordinate systems, namely rectangular, cylindrical, and spherical are outlined.
Journal ArticleDOI
Test zone field compensation
D.N. Black,E. Joy +1 more
TL;DR: Test Zone Field (TZF) compensation as discussed by the authors increases antenna pattern measurement accuracy by compensating for extraneous fields created by reflection and scattering of the range antenna field from fixed objects in the range.
Journal ArticleDOI
Near-field qualification methodology
TL;DR: A methodology that is a combination of analysis, computer simulation, component certification, self-tests, and comparison tests is presented for the accuracy qualification of near-field antenna measurement ranges.
