Self consistent loop antenna theory

An analytic theory of idealized finite loop antennas with an arbitrary current distribution was formulated. Computational steps required for the determination of the antenna current, consistent with the perfectly conducting antenna surface, are outlined. The isolated antenna in free space, and the effects due to the Faraday shield, the wall and the plasma are considered. All the necessary antenna parameters can be obtained if the plasma surface impedance is known. The concept of the cross fin antenna, which combines wave launching and Faraday shielding in a single composite structure, is introduced.
