A Numerical Modeling Study of the Transmission Line Antenna for Use as an HF Combat Survivable Shipboard Antenna

Abstract

This thesis investigates computer numerical models to improve combat survivability for HF shipboard antenna systems. The trend for the next generation of ships will be the elimination of tall and large structures to make antennas more survivable during combat. The use of a transmission line antenna on the bow and the stern of a ship seems to be a good candidate for solving these problems. The ship and antennas are modeled using wire grids. The computer models are developed by the Numerical Electromagnetics Code (NEC). Average power gain, input impedance, and radiation patterns of driven antennas are presented.
