Arrays of Unequal and Unequally Spaced Dipoles

The quantitative determination of the circuit and field properties of arrays of parallel, non staggered dipoles is treated theoretically and experimentally when the lengths of the elements and the distances between them may differ greatly. The simultaneous integral equations are replaced by approximately equivalent algebraic equations which are used to determine the coefficients of a simple three‐term approximation of the currents. Theoretical distributions of current. self and mutual admittances, field patterns, and other properties of simple two‐element and five‐element arrays are shown to agree well with measured values. Coupled elements ranging in length from longer than a wavelength to a small fraction of a wavelength are included in the study.
