Abstract: Mechanical and electrical test results of a high power two-patch array antenna [ARL Invention pending ARL-07-18, Ly, et al.] are presented. The mechanical test was run for 55 minutes for each axis of the antenna. The electrical test was conducted using a high power RF source (>1 KW) with single and two-patch array antennas. Although the first mechanical test results indicated that the screws of the antenna cover are loosened about 1/4 turn, and right angle connectors inside the antenna enclosure box were loosened about a fraction of a turn, the antenna still sustained all functional operations. The antenna uses air dielectric to endure a high average power for the system that operates at S-Band in order to neutralize unattended microwave devices. This development is to fulfill part of the Army Technology Objective (ATO), Network Centric Warfare for the U.S. Army Communications-Electronics Research, Development, and Engineering Center (CERDEC), and Research and Development Engineering Command (RDECOM).
