【摘要】 本文提出了一种侧面馈电的对跖Vivaldi天线,讨论了其设计方法,利用CST高频电磁仿真软件对其结构尺寸进行了仿真分析,并设计了加工了工作频段为1.5～5GHz的侧面馈电的对跖Vivaldi天线实物,测试了其阻抗和辐射特性,实测结果与仿真值吻合良好。与传统的微带正面馈电的对跖Vivaldi天线相比,侧面馈电的对跖Vivaldi天线能有效的利用了天线平面,减小了天线面积。更多还原

【Abstract】 This paper presented the design of a side-feeding antipodal Vivaldi antenna. The dimensions of the antenna have been simulated and analyzed with high-frequency electromagnetic simulation software CST. A sidefeeding antipodal Vivaldi antenna for 1.5～5 GHz was designed and fabricated. And its impedance and radiation characteristics have been measured. There is a good agreement between the measured and simulated results. Compared with the conventional microstrip-front-feeding antipodal Vivaldi antenna,the side-feeding antipodal Vivaldi antenna can reduce the antenna’s areas effectively.更多还原
