A Feasibility Study of a Shipboard Combat Survivable HF Antenna Design.

Abstract

This thesis investigates the feasibility of a shipboard combat survivable HF antenna design. The antenna is modeled as a rectangular volume excited by a square patch atop a monopole centered at one of the volume's faces. Several computer models of the driving antenna are modeled with the Numerical Electromagnetics Code (NEC) and compared. Scale models of the driving antennas are made and their impedance measurements compared to NEC computer models. Input impedances and radiation patterns of the survivable antenna are presented which indicate adequate performance given a 3:1 SWR. Keywords: Combat Survivable Antenna; and Computer Modeling of Antennas.
