The current distribution and input impedance of cylindrical antennas

Karsa, Ketut January 1960 (has links)
A critical discussion of various theories of cylindrical antennas is given* It is shown that the Hallen-King theory is of a semi-empirical nature. Both the current distribution and input impedance derived from this theory depend on a semi-empirical choice of an expansion parameter. It is also shown that the Hallen-King "slice generator" cannot be used to represent the effect of the transmission line. A theory which correctly accounts for this effect is developed and theoretical formulas are developed for both the current distribution and input impedance. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
