A Study of LF (Low Frequency) Top-Loaded Monopole Antennas Using Numerical Modeling Techniques. Comparison to Scaled Test Model Measurements

Abstract

This thesis studies the electrical properties of a low frequency top- loaded monopole antenna. Several configurations of the antenna are developed using numerical modeling techniques. The electrical properties are calculated and compared with a set of measurements of a scaled test model. The results are presented in the form of design curves and comparison tables. It is important for the U.S. Navy to have a reliable VLF and LF communication systems for world wide coverage. A need exists to increase the power handling capacity and the bandwidth of the existing VLF-LF antenna systems. This study provides the validation of numerical modeling techniques for future simulation of VLF antennas with corona rings. This will permit the design of improvements in the power handling capability by extending the onset of corona. Keywords: Theses; Method of moments.
