Electrical and mechanical uncertainty study in cylindrical near field antenna measurement systems

A simulator has been implemented for calculating the errors in the measurement parameters of the AUT in a cylindrical near field antenna measurement system. The simulator changes the parameters of the measurement system introducing deterministic and random errors and evaluating the acquired field through the near field generated by the array of dipoles. Afterwards, it calculates the different radiation parameters and extracts the results. In addition, through the comparison between the results achieved and the infinite far-field the deviation on the final outcomes could be determined. Therefore, this simulation tool allows quantifying a priori the value of the systematic error and the uncertainty introduced in the measurement system.
