As far as I am concerned, all NFC controllers are sold with in-built antenna in the PCB. If you can somehow source the PN532 NFC chip only(without any board) that may fulfill your purpose. There are some more NFC ICs such as STMicroelectronics M24LR04. It has two pins for the antenna coils. Antenna coil (AC0, AC1)
These inputs are used to connect the device to an external coil exclusively. It is advised not
to connect any other DC or AC path to AC0 or AC1.
When correctly tuned, the coil is used to power and access the device using the ISO 15693
and ISO 18000-3 mode 1 protocols. You may consider getting that too.
