Hi, I am trying to make the MFRC522 (https://www.nxp.com/documents/data_sheet/MFRC522.pdf) to work with a taoglas 50-Ohm antenna (http://taoglas.com/images/product_images/original_images/FXR.01.07.0100C.A.pdf)

To start I based my schematic and layout in the arduino RFID board but the problem here is that this board uses a PCB antenna and the circuit is composed with EM filter and impedance matching.

I think that as I am using a 50-Ohm antenna, I don´t need to build the impedance matching part, but the problem is that I can´t find a place I can get a circuit for MFRC522 with a 50-Ohm antenna.

I appreciate all the help!

Thanks!

After a long night I figured out what to do.

This PDF has a detailed info about how to implement what I wanted.
