Hello sir, I am trying to implement NFC functionality to my PCB. I am thinking about PN5321 and PN5180. But I have some confusion about them. PN5321 has 3 wire antenna and PN5180 has two wire antenna. I want to use external antenna. But facing problem about antenna tunning. I have no data for the external antenna. How can I manage it??

On the other hand these NFC chip are quite complex to design and expensive. Please if there any low cost and simple design IC available, I need to know.
