| Abstract(in English) | Precise determination of antenna phase centers is crucial to reduce the gain uncertainty in the three-antenna method, particularly operated over a short-rangesuch as a 3-m radio anechoic chamber, where the distance between the phase center and the aperture plane (the most common reference) is not negligible in comparison with the propagation distance. The phase centers of horn antennas has been automatically measured in a radio anechoic chamber and the absolute gain of horn antennas have been thereby evaluated with the three-antenna method. Then the gains, polarization, and radiation pattern of space-borne antennas low-, medium-, and high-gain X-band antennas for a micro-sized deep space explorer PROCYON were measured with the horn employing the polarization pattern method. Uncertainties in the gain were evaluated in accordance with ISO Guide to the Expression of Uncertainty in Measurement: 1995. |
