摘要： The invention relates to antenna elements for the UHF and VHF range for antennas of an airborne vehicle with empennage parts. These antenna elements are integrated into the empennage parts (L) which are made of a dielectric material and are configured in such a way that they radiate directionally broadband in flight direction. The empennage parts are made, for example, of ceramic, and the antenna elements are embedded therein or are applied to their surface.The antenna elements (A) are preferably expanding Vivaldi-type slot radiators that are halved along their axis of symmetry and use the airborne vehicle (F) as an electrical mirror.Arranging the antenna elements in the area of the rudder maximizes both the aperture and the distance between the phase centers of the individual elements, but no additional volume is required for the antennas.
