本文分析了对角喇叭天线的特性，结合切角正方喇叭天线的原理改进了它的激励方法，设计制作了一种８ｍｍ波段改进的对角喇叭天线。分析测试结果表明：该天线的Ｅ面和Ｈ面的辐射方向图基本相同，可用于毫米波导引头和末敏探测器中的天线初级馈源。
This paper analyzes the characteristics of the diagonal horn antenna, combined with the principle of the square horn horn cut angle to improve its excitation method, designed a 8mm band improved diagonal horn antenna. The analysis and test results show that the radiation pattern of the E-plane and the H-plane of the antenna is basically the same and can be used for the antenna primary feed in the millimeter wave seeker and the end-sensitive detector.
