Low-Uncertainty Characterization of a Predictable Active and Broadband Antenna

A detailed description of the calibration of a wideband reference electromagnetic field radiator consisting of the combination of a comb generator and a biconical antenna is offered. Calibration is based on the joint use of measurements of the comb generator power and simulations of the biconical antenna radiation parameters. An original aspect of the contribution is the quantification of uncertainty of both the comb generator power measurement and electromagnetic field prediction. Evidence of the validity of the uncertainty quantification is provided by a comparison between far-field measurements and predictions.
