Comparison of the Normalized Maximum Field Strength Using E-Field Probe and VNA Methods in a Reverberation Chamber

We report a comparative study on the maximum field strength in a reverberation chamber using a vector network analyzer (VNA) and a field probe. The measurements are performed in a reverberation chamber with a lowest usable frequency around 80 MHz. The time-domain (inverse Fourier transform) and frequency-domain methods are adopted in the VNA measurements. Measurement results show that these methods agree well with each other with reasonable differences. The field uniformity is also given. Discussion on different methods is finally summarized, which shows that the VNA-based measurements can collect more samples and reduce the overall uncertainty.
