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!
My question is what is the circuit I need to build between the MFRC522 and the Antenna. And what is the values of the components.
