Abstract :
Hallen´s integral is used to study the effects of adding hemispherical end-caps to a half-wavelength dipole. The current distributions on a-half-wavelength dipole with the end-caps and another without them are compared. A similar comparison is carried out for the impedance calculations. It is found that introducing end-caps and modeling the feed with a pulse generator results in a smoother current distribution and significantly improves the convergence of the input impedance.<>
