Abstract :
Characteristic mode theory as formulated in the works of Garbacz and Turpin (1971) and Harrington and Mautz (1971), has been used in a variety of applications, including radiation and scattering analysis and pattern synthesis. In this work, the theory of characteristic modes was used to analyze the input impedance and currents of a two-arm spherical antenna. Suggestions were given on improving broadband behavior of an antenna based on the analysis.
