We present a mathematical model for shielded loop resonators. The model implies equivalent circuits for coaxial as well as flat Faraday shielded resonators under both balanced and unbalanced termination conditions. Expressions for impedance derived from the model are shown to agree well with observation using two test experimental resonators in a variety of experimental conditions.
