Theory of Loop Antenna with Leakage between Turns

The theory of the receiving loop antenna of two turns with distributed leakage, conductive and reactive, is developed. Equations are derived for currents and voltages along the loop and at the terminals. For terminal currents and voltages the effect of leakage may be expressed by means of a single function H, and the loop may be represented by an equivalent two-mesh circuit of lumped constants. The effect of leakage upon the Q of a loop is discussed, and methods are described for the precise measurement of Q in the presence of leakage. Experimental applications are described.
