The possibility of applying a recently proposed emission source location method, which is based on CISPR measurements, to sources with arbitrary directional current components is studied. We propose a new finding algorithm in which the horizontal and the vertical current components are estimated at the same time by taking into account the contribution of horizontal current components when calculating the vertical electric field. As a result of experimental verification by using two spherical dipole antennas as ideal emission sources, estimated values show good agreement with the original ones in the frequency range from 300 MHz to 1GHz, where the position estimation deviation Ad was less than 0.15 m, the amplitude estimation deviation ？j was less than 2.1 dB, and furthermore the angle of current direction could be estimated. Consequently, this method with the presented new algorithm can be applied to find radiated emission sources even when the current components point to arbitrary directions.
