25/9/2012 · I have also noticed that even If I completely tuned an antenna at 50ohms my RFID carrier frequency (13.56MHz) slightly distorts but if I load a pure 50ohm resistor the output has minimal distortion. I also designed a 6 turn spiral antenna at 100mmX100mm where it is impossible to tune the circuit to 13.56MHz at 50 ohms using parallel resonance topology.
