The problem considered in this paper concerns with the study of the theory of characteristic modes applied to a conducting sphere. For this canonical case modes are obtained analytically. This work help us to understand better how the theory of characteristic modes works on this structure to reveal interior (cavity) and exterior (radiating) resonances. This knowledge will be used in future work to explain the radiation and the resonances appearing in dielectric resonator antennas.
