Abstract
In one embodiment, the present disclosure describes a flared antenna where the upper portions of the prongs are separated into a plurality of spaced apart parallel fins. The parallel fins disposed on the energized prong are energized by a common electrical feed, such as a coaxial transmission line that enters the energization region of the energized prong. The use of separate fins allows a wider range of tuning to gain greater BW and scan performance for a given equivalent design, since each fin pair may be designed independently from the other fin pairs in that flared antenna. The flared antenna may be a Vivaldi antenna, a stepped notch antenna or some other flared shape.
