摘要
针对平衡对拓Vivaldi天线存在方向图不对称及增益低的缺点,在分析和设计常规平衡对拓Vivaldi天线的基础上,通过加载半椭圆介质板和开不对称半椭圆槽,设计了一副工作在10~20GHz的天线并进行了仿真分析。结果表明,该天线方向图保持良好对称,方向图E面峰值偏移现象得到显著抑制,改进后的天线具有较高的增益和较强的方向性。
Aiming the faults of asymmetric pattern and the low gain of balance antipodal Vivaldi antenna, in basis of analysis and design of the conventional balance antipodal Vivaldi antenna, by loading the semi elliptical dielectric plate and opening asymmetric half elliptical groove, a novel antenna was designed and simulated within 1-20 GHz. Results show that the direction patterns of the antenna maintain good symmetry. The phenomenon of E peak shifting can be inhibited. The modification antenna has high gain and strong directionality.
