摘　　要：基于非周期天线理论,通过在传统Vivaldi天线的辐射区加载槽线,设计了一种新型Antipodal Vivaldi天线,显著提高了天线的特性。结果表明,该天线可实现对IEEE802.11a、b、g标准的完全覆盖,应用频带在2.26～2.6GHz和5.7～6.1GHz频率范围内,驻波VSWR均低于1.4,增益达到约7.5dB,方向性良好,具有良好的应用价值。In view of the overly sparse current distribution of antipode Vivaldi antenna on metal gradation surface,the slot-line is loaded in antenna radiation zone to solve the problem.Simulation and practical measuremen prove that to the antipode Vivaldi antenna designed by this method can realize well to IEEE802.11 a,b,g standard full coverage,the application frequency band in 2.26～2.6 GHz and in the 5.7～6.1 GHz frequency range,VSWR is lower than 1.4,gain may achieve about 7.5 dB with good directivity.The antenna is of application value.
