Relating to the radiated emission sources finding method utilizingCISPR emission measurement system, which uses only amplitude datawithout phase data, the applicability to sources with arbitrarydirectional current components was studied. We propose a new findingalgorithm in which the horizontal and the vertical current componentsare estimated at the same time by taking into account the contributionof horizontal current components when calculating the vertical electricfield. As a result of experimental verification by using two sphericaldipole antennas as ideal emission sources, estimated values show goodagreement with the original ones in the frequency range from 300 MHz to1 GHz, where the position estimation deviation Δd was less than0.15 m, the amplitude estimation deviation Δj was less than 2.1dB, and furthermore the angle of current direction could be estimated.Consequently, this method with the presented new algorithm can beapplied to find radiated emission sources even when the currentcomponents point to arbitrary directions
