Numerical Models of New HF Shipboard Communication Antenna Systems for Improved Survivability.

Abstract

There are many shipboard communication antenna problems where the number, type, location, or survivability of a given antenna in the system is a parameter which can be varied to determine the overall optimal system. This thesis investigates computer numerical models for improving the time that an HF shipboard combat survivable antenna system can endure in a given environment. The future generation of ships will have low profile combat survivable antennas; an interim solution for present ships is the elimination of fragile HF antennas by exciting existing masts. The antenna is modeled as a mast with dimensions 24 x 3 x 3 meters. Several computer models of the driven antenna are modeled using the Numerical Electromagnetic Code (NEC). Input impedances and radiation patterns of the antenna are presented.
