Shipboard Combat Survivable HF Antenna Designs.

Abstract

This thesis investigates the feasibility of two shipboard combat survivable HF communication antenna designs. Both antennas are modeled as a rectangular volume, which in one case is excited by a square patch atop a monopole, placed at various spacings from the center of one of the volume's faces, and in the other case is excited by a wire which is connected between the center of a face that is created by a rectangular shaped notch and a perfect ground plane. Several computer models of the two configurations for either different spacings between the patch monopole and the rectangular volume, or different notch sizes, are modeled with the Numerical Electromagnetics Code (NEC) and compared. Input impedances and radiation patterns of the two survivable antennas are presented. Both antennas are evaluated against a 3:1 Standing Wave Ratio (SWR) criterion. (Thesis)
