A novel balanced antipodal Vivaldi antenna (BAVA) with high gain and enhanced radiation parameters is proposed in this paper. The outer edges of the flare are modified by a binomial curve to broaden the impedance bandwidth. A modified metal director is adopted to improve the antenna gain and beam-tilting. The measured results show that the proposed BAVA achieves a bandwidth from 2 to more than 40 GHz with peak gain > 0 dBi and > 1 dBi over the 8–40 GHz range. The squinting beam of E-plane is less than 5◦ from 4 to 40 GHz and less than 3◦ from 22 to 40 GHz.
