The imperfectly conducting cylindrical transmitting antenna: Numerical results

The complex wave number, the distribution of current, the admittance, and the radiating efficiency of cylindrical antennas made of imperfect conductors are evaluated numerically from a previously derived theory[1]. The quantity
2\lambda r^{i}/\zeta_{0}
(where
r^{i}
is the resistance per unit length,
\lambda
is the free-space wavelength, and
\zeta_{0} = 377
ohms) is used as the parameter in a range that extends from zero to 200. Extensive graphs and tables are given.
