摘要
常规vivaldi天线存在后向辐射大，主辐射方向增益低的缺点。通过优化常规vivaldi天线贴片形式的方法，改变天线表面的电流分布，得到其改进形式-兔耳形vivaldi天线。对改进型vivaldi天线的电性能进行了分析，设计并制作了一付工作在6～18GHz的改进型vivaldi天线，与常规vivaldi天线相比，天线增益在整个频带内均有显著的提高。
For great back-radiation and low gain in the main-direction of traditional vivaldi antenna, a modified form named as Rabbit-Ear antenna is proposed by changing the current distribution on the optimized regular vivaldi antenna patch. The antenna operating at the bandwidth of 6-18 GHz is designed and fabricated, and its electronical characters is analyzed. Comparsing with traditional vivaldi antenna, the gain of the modified antenna is improved at the whole bandwidth.
