Abstract: A broadband multi-element antenna having desirable phase, standing wave and polarization characteristics is disclosed. The antenna is arranged as a plurality of airfoil shaped elements located in radial planes about a central axis with the element peripheries collectively defining a horn shaped surface--centrally disposed of which is a ground plane member of preferably truncated conical shape which includes electrical feeding arrangements having in phase and out of phase element coupling. The antenna is suitable for radar, satellite, and other precision uses including military applications.
