Hello,
I'm trying to design an RFID Cornhole board with RFID tags inside the bags and antennas under the board. The IC my team has purchased is the TRF7970A and we also have the RF-HDT-DVBE-N2 tags. We are planning on using the multiplexer system from this document (https://www.ti.com/lit/an/sloa167/sloa167.pdf?ts=1663710980042).
I need a general direction on how to design the copper antennas and their respective tuning circuits. I am also in need of circuit schematics for the TRF7970A and possibly the PE42440. The PE42440 has 0 in stock so I would appreciate a recommendation for a similar product.
Brian
