摘要：
Antenna calibration is classically performed assuming far-field conditions. With increasing computational power available, numerically demanding near-field to far-field transformation algorithms are becoming more important. This paper shows how modern near-field to far-field transformation algorithms can be used to precisely calibrate antennas. In addition to the actual algorithm, this paper also demonstrates how the calculated far-field data can be used to calculate the electric field strength in front of arbitrary antennas. This post processing step is of special importance for the traceable calibration of electric field strength meters.
