Abstract
For many years the cylindrical dipole and circular loop have been thought of as the basic radiating elements. Due to its relative simplicity the study of the cylindrical dipole is quite complete, but owning to the degree of complexity, progress in the theory of the loop has been slower. In recent years the isolated circular loop antenna of arbitrary size has been the subject of mathematical and experimental analysis [7[, [6]. It was not until 1970 that the first complete and general mathematical solution for the mutual admittance of two arbitrary size coaxial circular loop antennas was published. The problem was formulated by Adler in terms of coupled integral equations for the current distributions on the loops [1]. The equations were solved using the Fourier series representation of the current distributions. The study presented here is the next logical step beyond the work of Adler. Using his current equations the current distributions are calculated at each point around the two loops. The input admittance, electric field and power gains are calculated. Radiation patterns and the loop current distributions are plotted for two cases: (1) both loops driven and (2) one loop acting as a short circuited parasite.
