Vivaldi Aerial 是非周期性连续缩放天线结构类别的新成员，因此，理论上它具有无限的瞬时频率带宽。该天线具有显着的增益和线性极化，并且可以符合恒定的增益与频率性能。其中一种设计在从低于 2 GHz 到高于 40 GHz 的瞬时频率带宽上具有大约 10 dBI 增益和 ¿20 dB 旁瓣电平。
The Vivaldi Aerial is a new member of the class of aperiodic continuously scaled antenna structures and, as such, it has theoretically unlimited instantaneous frequency bandwidth. This aerial has significant gain and linear polarisation and can be made to conform to a constant gain vs. frequency performance. One such design has been made with approximately 10 dBI gain and ¿20 dB sidelobe level over an instantaneous frequency bandwidth extending from below 2 GHz to above 40 GHz.
