Abstract

A novel balanced antipodal Vivaldi antenna (BAVA) with high gain and good directivity is proposed in this paper. The outer edges of the flare are modified by a binomial curve to broaden the impedance bandwidth. A metal director is adopted to improve the antenna gain and directivity. The measured results show that the proposed BAVA achieves a bandwidth from 2 to more than 40 GHz with peak gain >0 dBi and >10 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.
