Hi Wingros,
So the antenna tuning in this case should be done to match with 20Ohm or 50Ohm for maximum reading distance (not working on a battery).
Please suggest.

@Wingros
Would be great to get a response here.

Hello Wu,
20OHM impedance is between TX line & antenna;
50OHM impedance is between signal line & GND.
Understand my explanation?
