| Abstract(in English) | Two calibration methods with the extrapolation technique are proposed to calibrate the actual gain for EMI antennas above 1 GHz. In this method, the S_<21> at the infinite distance between antennas are estimated from the S_<21> values measured at near-field region by the least squares method. The calibration results of two kinds of double-ridged guide horn antennas (DRGAs) show that the accuracy of the proposed method depends on the directivity of the antenna under calibration and that the method can yield the actual gain with an error less than +0.3 dB/-0.2 dB even at a small semi-anechoic chamber with a metal ground plane. |
