Abstract :
We present a statistical theory for estimating the directive characteristics of unintentional emitters based and the electrical size of the device. We compare this theory to directivity derived from pattern measurements in an anechoic chamber. We also use this theory to predict the maximum radiated fields based on total radiated power measurements in the reverberation chamber
