Abstract
EMI measurement at 3m using biconi-log antenna is simulated, and compared to the corresponding EMI measurement using half wave dipole antenna. As a result, when the distance between equipment under test(EUT)and the center of biconi-log antenna is defined as the measurement distance, difference between the measurement values by the biconi-log antenna and by the half wave dipole antenna become small. But even in this condition, maximum of the difference may become 3dB in 200-300MHz.
