Dear Friends,

 

I am working with MFRC522 in our project. I can't properly design RFID coil antenna for our project. I am try to design a circular antenna. I am attached the pdf which I refer for this. 

I used the reader circuit as same as MFRC522 reader.

 

Inductance - 2.2 micro henry

Number of turns I get from the equation in page number 46. 

 

I think my problem is can't find the tuning capacitance value of the antenna.

 

With Regards,

Sunil
