Abstract:
At least one example embodiment provides a near field communication (NFC) antenna matching network system connected to an NFC transceiver. The NFC antenna matching network system includes a matching circuit connected to first and second antenna terminals and to the NFC transceiver. The matching circuit is configured to match impedances of the NFC antenna network matching system and the NFC transceiver. The NFC antenna matching network system includes a plurality of NFC antennas connected in parallel with the first and second antenna terminals. Each of the NFC antennas includes a source coil and a resonance coil. The source coil is connected between the first antenna terminal and the second antenna terminal. The resonance coil is physically separated from the source coil and configured to exchange signals with the source coil via inductive coupling.
