ABSTRACT:
A combined antenna system mounted in a nose randome of an aircraft for both radar and ESM signals. A flat plate waveguide antenna, a twist panel, a selective reflector, and a feed are aligned along a longitudinal axis in the randome. The polarized electromagnetic energy is twisted 45 degrees; and the selective reflector passes the twisted electromagnetic energy and reflects energy polarized in planes substantially different than the twisted plane.
