摘要：
An ultra-wideband (UWB) wide-scanning dualpolarized Vivaldi antenna unit is proposed in this paper. Vivaldi antennas always suffer from the high-profile problem. As a solution, the novel pendulum-shaped slots are designed, which notably reduces the profile and enhances the wide-scanning ability. Thus, the proposed dual-polarized Vivaldi antenna unit achieves +/- 60 degrees beam scanning in E/H/D planes with an active VSWR below 2.5 in 6 similar to 18GHz. The orthogonal port coupling during beam scanning is lower than -30dB in E/H planes, -10dB in D plane. Computed performances prove that the proposed dual-polarized antenna unit is of great potential to be employed for large-scale Vivaldi arrays.
