【摘要】 提出了一种尖劈形介质加载喇叭模型。作了理论分析和实验验证,均表明加载介质确有展宽普通喇叭E 面方向图主瓣、降低副瓣的改善效果,副瓣电平能压低到25dB 以下。得到了一种结构简单而高效的喇叭馈源。更多还原

【Abstract】 A model of wedge(or V-shaped)dielectric loaded horn isintroduced in this paper.Theoretical analysis and experiment about it aregiven and show that the loaded dielectric do have the ability to widen themainlobe of general pyramid horn’s E directional pattern and lower itssidelobe level.The sidelobe level may be lower than 25dB.A simple and ef-ficint pyramidal horn feeder is available.更多还原
