My RFID chip impedance is 20-200j, and the antenna impednace is shown in the figure. It changes with the antenna length.
To gain the best match, the antenna impedance should be 20+200j.
From the figure, I can't match both the resistance and the reactance. What's the best length I can choose to match better?
Should I choose to match the the imaginary part? So that I get the impedance 100+200j for the antenna.
Thanks.
