Two representations for the current on an isolated antenna in an arbitrary, homogeneous, isotropic medium have been obtained. These are the polynomial and the trigonometric forms, each with an exponential multiplier. The representations are used for solving coupled integral equations for two antennas in a dissipative medium. Measurements made over a wide range of the parameters of the medium, antenna lengths, and separations (in the case of coupled antennas) indicate a close agreement between the computed and observed values for the admittance and the current and charge distributions for isolated as well as coupled antennas.
