Passive Magnetic Antennas, TX-Loop Antennas
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.
