title: Probe-Position Error Correction in Planar Near Field Measurements at 60 GHz: Experimental Verification.
abstract: This study was conducted to verify that the probe-position error correction can be successfully applied torealdata obtained on a planar near-field range where probe position errors are known. Since probe position-error correction is most important at high frequencies, measurements were made at 60 GHz. Six planar scans atzpositions separated by 0.03 A were obtained. The correction technique was applied to an error-contaminated near field constructed out of the six scans according to a discretized periodic error function. The results indicate that probe position errors can be removed fromrealnear-field data as successfully as fromsimulateddata; some residual errors, which are thought to be due to multiple reflections, residual drift in the measurement system, and residual probe position errors in all three coordinates, are observed.
