Air Force Probes Enhanced Antennas

By Robert H. Williams
 Air Force-funded research on holographic impedance surfaces is expected to yield advanced antennas that will give aircraft improved aerodynamics.

The cutting edge study is being performed by HRL Laboratories in Malibu, Calif., under an Air Force Office of Scientific Research contract.

“We are using a design technique that is similar to how people make holograms. We can potentially make antennas that are completely flush with the surface of the aircraft, but have the same or better performance as those that protrude from the aircraft using today’s techniques,” said Daniel F. Sievenpiper, lead researcher at the lab.

This technology also holds out the promise of eliminating on board radar interference. The Air Force’s Arje Nachman said that the tail of an airplane could be covered with a “suitably crafted impedance surface in such a way that the antenna beam ‘flows’ around the tail as if weren’t there.”
