Emission Characteristics of Electrically Small Radiating Sources from Tests Inside a TEM Cell

An electrically small radiating source of arbitrary nature may be modeled by an equivalent-dipole system consisting of three orthogonal electric dipoles and three orthogonal magnetic dipoles, each excited with arbitrary amplitude and phase. A method of determining the individual dipole moments and the cross-components of such a dipole system, by tests inside a transverse electromagnetic (TEM) cell, is presented along with some experimental results.
