Mutual and Self-Impedance for Colinear Antennas

In Part I a two-element colinear array, consisting of identical center-driven antennas of finite radius, is discussed as a boundary-value problem. A formulation is given for the distribution of current when the antennas are driven symmetrically and antisymmetrically. From these data the impedance properties of the array may be deduced. In Part II a simplified, but much less rigorous investigation of the same problem is presented. The more important results include curves and tables for mutual and self-impedance.
