This isn’t a solution to your problem, but I had similar challenges with UHF RFID at 865 MHz. In UHF RFID the tags are electrically short dipoles modulated by the chip impedance. I thought it would be impossible to measure the two way traffic due to the huge difference in the TX and RX signal amplitudes.
I solved this by making a tiny hole through the tag ...
