Abstract:

The coupled integral equations for the transverse and axial currents in an electrically thick tubular antenna are derived for the case in which it is driven along an infinitesimally narrow circumferential gap by an emf which is allowed to vary along the circumference. The emf is assumed to be maintained either on the outside surface only, or on the inside surface only, or on both the surfaces of the tube, as in the conventional treatments of antenna theory. For the special case of a driving emf which is uniform around the circumference, the transverse currents are not excited and the integral equation for the total axial current is shown to reduce to the known results both for the case in which the emf is maintained on both the outside and the inside surfaces of the tube and for which it is on the outside surface only.
