In this paper, a novel near-field cable-free impedance and gain measurement technique for electrically small antennas is proposed. In this technique, with the electrically small antenna placed in the near-field region of the probe, the properties of this antenna are extracted by measuring the signal scattered by it when it is loaded in turn with three known loads. The determination of the antenna...
In the frame of the activity ldquoantenna measurement techniques and facility sharingrdquo of the EU network ACE ldquoAntenna Centre of Excellencerdquo substantial attention has been devoted to perform a series of antenna measurement facility comparisons. The activities have been performed using SATIMO dual ridge horns in L, S and C band (SH800) and in Ku and Ka band (SH2000). This paper discuss the...
This paper presents a detailed investigation of the pattern integration technique, which is a method employed at the DTU-ESA spherical near-field facility for calibration of standard gain horns. Furthermore, this study also describes the comparison of the pattern integration technique with the three-antenna technique. In order to make a complete evaluation, the analysis also includes the uncertainty...
