摘要
文章设计了加载周期波纹与三层介质透镜的对踵Vivaldi天线(antipodal Vivaldi antenna with a periodic slit edge and three-layer trapezoid-shaped dielectric lens,PSEAVA-TDL),拓展了传统对踵Vivaldi天线(conventional antipodal Vivaldi antenna,CAVA)的低频带宽,改善了CAVA的辐射性能,在4、16 GHz处天线的端射增益分别提升了2.1、7.0 dB。宽频带内该天线辐射性能稳定,方向性良好。该天线经过加工测试,实测结果和仿真数据基本一致。
A modified antipodal Vivaldi antenna with a periodic slit edge and three-layer trapezoid-shaped dielectric lens(PSEAVA-TDL)is proposed.The lower-end limitation of conventional antipodal Vivaldi antenna(CAVA)is extended and the radiation performance is improved.At 4 GHz and 16 GHz,the end-fire gain of the antenna increases by 2.1 dB and 7.0 dB compared to CAVA respectively.The PSEAVA-TDL possesses stable radiation characteristics in a wide frequency range.The CAVA and PSEAVA-TDL are fabricated and measured,the measured results agree well with the simulated ones.
