MATHEMATICAL ANALYSIS OF ELECTROMAGNETIC RADIATORS FOR HIGHWAY ADVISORY RADIO. VOLUME I: VERTICAL MONOPOLES
This report deals with the mathematical analysis of the radiation characteristics of Highway Advisory Radio (HAR) vertical monopoles. There were two types of analysis considered in this effort. They were: (1) Modeling of the antennas by Method of Moments techniques to determine free space and perfect ground parameters. This was followed by an analysis of antenna radiation characteristics by use of a parallel plate capacitor model and Norton's Equations. (2) Modeling by an equivalent circuit representation which includes ground effects, geometric parameters and re-radiation characteristics of antennas mounted on arbitrary structures. These models were implemented in Fortran IV computer programs, and various runs were made to compare the predictions of the models with measured radiation characteristics of actual HAR monopoles. In general, the models confirmed the results of the field measurements.
