A vector network analyzer (VNA) with a bulk current injection (BCI) probe is proposed to measure the transmission coe-cient of a PCB. The purpose of developing such a measurement techniques is to predict the radiated emission for good correlation with the fully-anechoic chamber measured results. In this study, the proposed method is used to determine the radiated emission from a DC supply loop. Moreover, the proposed method can be further used to accurately predict the reduction of radiated emission from the improved DC supply loop. Electromagnetic simulations is also developed to conflrm the accuracy of the proposed techniques.
