On Improving Approximations for Current and Charge Distributions of Cylindrical Dipole Antennas.
Abstract
Approximate formulas are derived for the current and charge distributions on cylindrical dipole antennas. These formulas are distinguished from derivations of some other authors by being better representations, particularly near the ends and driving point of the dipole, and by being valid over a larger range of electrical lengths. The latter distinction is important in the study of single dipoles operated over a fairly broad band of frequencies, or in the normal operation of an array of dipoles of widely varying lengths. A typical array of this kind is the log-periodic dipole antanna. Sample calculations and graphs of current, charge, and admittance are provided for the purpose of comparing the new representations with the earlier derivations and with experimental results.
