Mutual comparison on calibration of free-space antenna factor for EMI antenna in 30MHz – 1GHz

This paper gives the results of mutual comparison of free-space antenna factors between NICT of Japan and RRL of Korea. To obtain the free space antenna factors, NICT use the curve fitting technique using standard antenna method, RRL use height scanning averaging in which the insertion loss depending on the height from ground is averaged. Although the maximum deviation between the values calibrated by two laboratories was 0.6 dB at 600 MHz in case of dipole, they were correspondent within the uncertainties of both institutes.
