Abstract: Even though several Vivaldi antenna designs have been discussed in the literature with a wide impedance bandwidth, the usable bandwidth is often limited by pattern degradation at the higher frequencies of the operating bands.The widest usable bandwidth achieved is around 30:1.This paper presents a bilateral Vivaldi antenna with a usable bandwidth of 50:1 (1-50 GHz).The bilateral form of the antenna and the optimization of the flares resulted in achieving this improved bandwidth.
