| Abstract(in English) | The delta-gap source and the magnetic frill generator are most widely used mathematical models describing the feeds of cylindrical antennas. For the delta-gap modeling, it has been known that the integral equation, including the electric field produced by the equivalent magnetic current existing over the gap as a part of the excitation function, give the solution for the external current separated from the internal current. However it has been solved only for infinitely long antennas. This paper treats a finite length cylindrical antenna numerically but precisely based on the the similar integral equation. Green's function is studied first with special care to the treatment of the singularity. Excitation functions for the external current and for the internal current are evaluated and their features are discussed. Finally, the convergence properties in the moment method analysis are investigate comparatively with approximate methods such as point matching method. |
