Practical Implementation of Probe-Position Correction in Near-field Planar Scanning Measurements



Jeffrey R. Guerrieri, Katherine MacReynolds, Michael H. Francis, Ronald C. Wittmann, Douglas T. Tamura


Planar near-field measurements require taking amplitude and phase data on an accurate and equal space grid on the plane in front of the antenna under test. The position accuracy on this grid has been determined to be '/50. As frequencies become higher, position on the planar grid becomes more difficult to achieve. This paper discusses the use of a laser-tracking device to provide position information in x, y, and z that can be used in position correction algorithms to correct for any displacement error in the actual measurement. This paper describes the physical implementation of a probe-position correction capability at NIST. Preliminary test results are presented and evaluated.
