Probe - Correction Coefficients Derived From Near-Field Measurements

Author: Gregory F. Masters

Probe correction is necessary in near-field measurements to compensate for non-ideal probes. Probe compensation requires that the probe’s far-field pattern be known. In many cases direct far-field measurements are undesirable, either because they require dismantling the probe from the near-field range set-up or because a far-field range is not available. This paper presents a unique method of deriving probe-correction coefficients by measuring a probe on a near-field range with an “identical” probe and taking the square root of the transformed far-field. This technique, known as the “Probe-square-root” method can be thought of as self-compensation. Far-field compensations are given to show that this technique is accurate.
