HFRA 1356

The HFRA 1356 is a passive loop antenna which is matched to a resonance frequency of 13.56 MHz with 370 kHz bandwidth (-3dB)

The purpose of the antenna is to produce defined magnetic fields at 13.56 MHz efficiently, i.e. to test near field communication devices (NFC) or RFID equipment.

NFC issues are described in the standards ISO 18092, ECMA 340, ETSI TS 102 190.
