I am aware of that, like I said, I'm new to RF, but I understand that without a non reactive part of impedance in the antenna, there's no power going into the antenna right? If the LC is at resonance, the impedance is infinite, therefore, there can be no watts. I am assuming the parallel R at resonance partly consists of the power radiated into space, and partly other effects of the current flowing through the LC tank. In the case of RFID, because the passive receiver is powered by the RF field, part of the power sent to the antenna is dissipated in the receiver circuitry through coupling. What I'm trying to figure out is: am I chasing the right thing when it comes to designing a matching network? and is the nanoVNA capable of measuring the real component of impedance at the resonant frequency with any accuracy.
