Abstract:

Approximate solutions are derived for current and charge distributions on center-driven, electrically thin, cylindrical dipole antennas. These solutions apply to electrically long dipoles for which the King-Wu three-term theory is apparently not sufficient, although they are equally useful for the shorter dipoles for which the three-term theory is completely satisfactory. They can apply to cases requiring treatment of a broad range of electrical lengths such as, for example, dipoles driven by pulsed rather than steady-state voltages and log-periodic arrays of dipoles. Current and charge distributions are graphed for ten dipoles whose electrical half-lengths cover the range 0.750.253.00 times the wavelength. These theoretical results compare favorably with available experimental values. Author
