The Insulated Linear Antenna-Revisited

Page 914.

Abstract:

In the past, the insulated linear antenna has been analyzed with an approximate transmission-line theory. The range of validity for this theory has not been established. In this paper, the finite-difference time-domain (FDTD) method is used to analyze the insulated monopole antenna. The validity of the FDTD analysis is established by comparison of results with accurate measurements for a variety of antennas. The FDTD analysis is then used to determine the accuracy of the approximate transmission-line theory. Graphs are provided to quantify the errors in the approximate theory as functions of the geometry and the electrical properties of the monopole antenna.
