Experimental Verification of the Weibull Distribution in a Reverberation Chamber

International Journal of Antennas and Propagation, 2019
A Weibull distribution has been proposed for the probability density function (PDF) of the magnitude of the E-field in a reverberation chamber (RC). However, the Weibull distribution has two parameters, and if the parameters are position sensitive, the ...
