Fast Sample Technique in Antenna Time Domain Near Field Measurement

In the practice of antenna time domain planar near field measurement, the probe moving step by step in each sample point is not acceptable for the huge time spending. The effect of measuring results in case of probe continuously moving in one dimension has been analyses in this paper. From simulation, it can be find that sample in the condition of probe moving continuously has almost the same measuring precision as sample in the condition of probe moving in step, and the probe moving speed can be even much faster than it in frequency domain. It means that time domain near field measurement can support fast sample, and has more efficiency than frequency domain near field measurement.
