The following table provides an overview of typical detection ranges with some
transponders.
Table 19: ULPM Card Detection Ranges 4090A10 HF Antenna
Typical
Detection
Range[mm]
MIFARE Ultralight (MF0ICU1) NXP Semiconductors 14.51 55
MIFARE Classic (MF1S50) NXP Semiconductors 14.04 55
MIFARE DESFire (MF3ICD40) NXP Semiconductors 15.37 45
iCLASS 32k HID Global 13.63 90
FeliCa RC-S962 Sony Corporation 13.52 85
Note: If the card detection range exceeds the actual read range, the reader may wake
up but not read the transponder successfully at this distance.
7.3.5 RF Properties
Provided is an overview on the RF properties of the 4090A10 HF antenna in
combination with the iCLASS SE Reader Module. The modulation waveforms were
measured at a distance of 10mm. Parameters may vary per unit due to component
tolerances. The compliance of the modulation waveforms is essential to ensure the
interoperability with various transponders in the field.
All measurements were performed in accordance to the ISO/IEC10373-6 standard.
Note: The following graph shows that at distances smaller than 12mm, the detuning of
the Reference PICC used for the measurement causes the field strength to decrease.
Observe similar behavior with transponders that introduce a loading effect of similar
magnitude.
