We have developed a far field free space antenna factor estimation method for broadband antennas. Our using method determined the far field antenna factor using amplitude center modified antenna factor estimation equation. In this paper, we show a measurement uncertainty of biconical antenna for electromagnetic interference measurement. Estimated expanded uncertainty (k = 2) of biconical antenna was...
Performance requirements for compact ranges are typically specified as metrics describing the quiet zone's electromagnetic-field quality. The typical metrics are amplitude taper and ripple, phase variation, and cross polarization. Acceptance testing of compact ranges involves field probing of the quiet zone to confirm that these metrics are within their specified limits. It is expected that if the...
Measurement methodology and theoretical equations to RCS and DeltaRCS determination are recalled and the measurement uncertainties are evaluated in this paper. Even if measurement uncertainties are generally not required for RFID, it is important to understand and to be able to determine the measurement uncertainty. Currently, manufacturers and testing laboratories present some results of RFID measurements...
The probe correction of near-field measured data can be considered to be composed of two parts. The first part is a pattern correction that corrects for the effects of the aperture size and shape of the probe, and can be analyzed in terms of the far-field main component pattern of the probe. The second part is due to the non-ideal polarization properties of the probe. If the probe responded to only...
