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。A model of wedge(or V-shaped)dielectric loaded horn is introduced in this paper.Theoretical analysis and experiment about it are given and show that the loaded dielectric do have the ability to widen the mainlobe of general pyramid horn's E directional pattern and lower its sidelobe level.The sidelobe level may be lower than 25dB.A simple and ef- ficint pyramidal horn feeder is available.
