H field probe with two decoupled loops

To achieve optimal performance, coils must usually be tuned to the Larmor frequency, e.g., by adjusting one or more capacitors or physical dimensions. Resonant frequency can be measured readily using a vector network analyzer (VNA) and a single loop probe with an S11 measurement (analogous to the dip meter measurement used in the past when VNAs were not cheap and portable). The coil’s sensitivity or SNR of the received signal is related to the ratio of loaded and unloaded quality factors (Q) [1]. With some corrections [2], Q can be measured using the same S11 measurement above, but it is…
