A measurement technique by using equally spaced dipole sensors is presented to estimate undesired electromagnetic source location emitted from electronic equipment in a short time. A compensation method for array element pattern is also proposed. Experimental values of the difference of the amplitude and phase between the received voltage of each array element and that of a single sensor placed at the same position of each array element of array sensor are obtained for the cases of 3-element and 5-element array sensors with the array spacing of 0.5 wavelength and 1 wavelength. It is also shown that the received voltage after compensation using experimental data agrees with the received voltage by scanning a single sensor within 0.4 dB in amplitude and 2.4 degrees in phase.
