The Analysis of General Axially Symmetric Antennas with a Coaxial Feed Line by the Method of Lines

Reinhold Pregla, Senior Member, IEEE

Page 1433.

Abstract:

The use of the method of lines in the analysis of various circular antennas--circular patch antennas and various forms of monopoles is proposed and substantiated. The antennas considered are fed by coaxial lines. Impedance/admittance transfer procedures are developed, which allow to calculate the antenna input impedance by a successive transfer from the aperture through the different sections. The described relations are also useful for other applications.
