Low-frequency loop antenna arrays: Radiation field of systems of horizontally oriented loops

Previously we calculated the impedance and antenna currents of loop arrays resulting from ground reaction and mutual interaction [1]. Here we make use of those results and develop a general theory of the radiation field for horizontally oriented loop arrays. Radiation patterns of a linear array of 100 horizontally oriented loops are computed numerically in their dependence on ground conductivity, distance, and current phase difference between adjacent loops.
