N2 - Mechanical antennas have garnered interest as a potential method of transmitting extremely low frequency (ELF) to very low frequency (VLF) radiation in a manner which possesses a high efficiency of radiation and a low form factor. In this paper, we investigate these claims by solving for the exact field solutions from one particular example, a rotational-oscillating charged thin spherical shell. The field solutions allow analysis of the radiation pattern, radiation efficiency, and spectral output as a function of several geometric and kinematic quantities of the sphere. The results indicate that high efficiency with a low formfactor appears to be plausible, assuming the required mechanical conditions for the motion can be achieved.
