Hello, 

The NTAG215 has a  50 pF input capacitance, for the rest of the values you are asking, you will need to check the AN11276 NTAG Antenna Design Guide to help you get the values for your desired antenna size.

I have gone through the document and would be really thankful if you could help me with the Ri value. I have to basically find the impedance of the chip without connecting it to the VNA. Also is there a evaluation kit which I can order?

Hello, 

The NTAG215 it's not a reader, it is a tag, so I believe you might have a confusion here as there are no evaluation kits of a tag, you can have one of the reader's evaluation kits and order some tags for you to develop.

I don't have to design a new antenna as I am trying to calculate the inductance of asbuilt antenna. Is the 50pF chip capacitance? or overall capacitance? Please reply
