| 摘 要： | 常规Vivaldi天线存在后向辐射大、主辐射方向增益低的特点。文中提出了在天线两侧开栅栏和尾部加抗流栅栏的优化方法,将天线金属贴片的表面电流汇聚于槽线部分,明显改善了天线的辐射特性,在350 MHz和830 MHz的增益分别达到5.7 dBi和8.7 dBi。通过对天线进行实物测试,其阻抗带宽为310~1 300 MH...

| Abstract: | For great back-radiation and low gain in the main-direction of traditional vivaldi antenna,the article proposes a method for the improvement and optimization of antenna structure by adding slots on the metal patch.By this method,the current can be forced to gather up along the taper-slot to improve the antenna radiation property.The gain of 350 MHz is 5.7 dBi while the gain of 830 MHz is 8.7 dBi.Vivaldi antenna is measured by Network Analyzer.The impedance bandwidth of measured data is covered from 310 to 1... |
