Title: Predicting radiation characteristics from antenna physical dimensions
Description: This report explains the fundamental theory and equations used in writing a set of software      applications which predict antenna radiation parameters. Each application predicts the      radiation characteristics of a particular type of antenna over a planar surface which serves as      a model of either earth or seawater. The radiation parameter predictions are based solely on      an antenna's physical dimensions, the properties of the underlying surface, and      electromagnetic theory. Existing electric field equations provide the basis for radiation      parameter predictions, and the accuracy of the predicted radiation parameters is totally      dependent upon the extent to which the electric field equations used realistically model the      actual radiated electromagnetic fields of the antennas. In addition to a review of applicable      electromagnetic field theory, this report is also intended to be a user's guide for the      corresponding computer applications. The appendices contain computer hardcopies of      sample calculations for several antenna types and remarks regarding the conformity of      predicted radiation parameters to expectations. Radiation parameters computed thus far are      consistent with expectations based on other computational programs and empirical      measurements.
