In this article, the transition from the mathematical model of the loop antenna to the mathematical model of a shielded loop antenna is presented. On the basis of the obtained model recurrence relations are derived, which make it possible to pass to the mathematical model of the multi-turn framework. With the help of the developed model, the analysis of the operation of loop antennas under the control of receivers with symmetrical inputs is carried out. The analysis made it possible to distinguish the groups «small», «medium» and «large» loop antennas relative to the wavelengths of the working band. For each group of frames, a recommendation is made on the number of turns of the coaxial cable.
