Calibration to facilitate the comparison of numerical and experimental data for an antenna

Abstract

A simple procedure to calibrate numerical data in a manner which allows for accurate comparison to experimental data is presented. A simple dipole is used to demonstrate the procedure. The numerical calibration procedure is essentially the same as the experimental calibration procedure which makes it possible to make good comparisons. The antenna, along with three calibration standards, are numerically modelled and experimentally measured. Standard S-parameter calibration procedures are used for both. The calibrated numerical data and the measured data are compared in terms of reflected voltage in the feed line. Agreement is shown to be improved significantly with the calibration technique.
