Breakthroughs in Low Profile Leaky Wave HPM Antennas

Abstract

This report presents the results of a 37-month program to discover, identify, investigate, characterize, quantify, and document the designs -and to predict performance characteristics of -novel low-profile leaky-wave High Power Microwave (HPM) antennas. Our primary focus was upon geometries employing forward-traveling, fast-wave, and continuous-type leaky-wave apertures conformable to various flat, singly-curved, and multi-curved surfaces. In anticipation of applications in Directed Energy Weapons (DEWs), we sought high aperture-efficiency geometries that yielded narrow-angle beams suitable for delivering high peak power densities against distant targets. New, improved, and more-compact designs for leaky-wave HPM antennas were identified, investigated, and advanced under this program. These antennas may help to solve the difficult packaging and system integration problems associated with HPM-based DEWs.
