Generalized equivalent circuit of a single-loop input receiving device

Consider input devices whose election system contains one resonant circuit. Communication schemes of the resonant circuit with the antenna and the input of the first cascade can be very diverse. However, despite the difference in communication circuits, all single-loop input devices can be represented as a generalized equivalent circuit presented in the figure.

Figure 6.1.   

        Y is the conductivity of the circuit;

        - conductivity of the input of the first cascade, recalculated to the contour;

        - voltage on the circuit, expressed through the voltage at the output  

For this, the circuit is represented as some complex conductivity Y. To the contour, taking into account the inclusion coefficient (transformation), m ₁ , m _{2 are} recalculated:

- parameters of antenna-feeder system - current generator with internal conductivity ;

- conductivity of the first cascade in the form of recalculated conductivity .
