AOE provides high performance phased array radiating element technology capable of multi-octave performance (9:1 +).
With wide scanning, dual polarization capability and near ideal cosine falloff, AOE’s proprietary element architecture has been employed in Radar, Electronic Warfare (EW) and Signal Intelligence (SIGINT) applications. Our custom Vivaldi/Notch antenna technology is optimized for several parameters to meet customer requirements including specified frequency range, minimized depth, and minimum return loss at a specified angle.
