目前大学天线教材中的角锥喇叭天线最佳尺寸设计曲线使用较复杂.本文导出了一个统一的最佳尺寸的简便公式,并有相应的单值曲线表示,对曲线的用法作了设计举例与比较. 问题的提出角锥形喇叭天线设计一般归结为给定工作波长入,方向系数G、主瓣宽度相等诸条件,要求设计出方向系数达到规定值,口径面最大相位差不超过规定值,喇叭颈与波导口吻合的喇叭最佳尺寸.现在大学天线课本中所用的设计方法是把角锥喇叭的方向系数变成
At present, the optimal dimension design curve of pyramid horn antenna in university antenna teaching materials is complicated to use.This paper derives a simple formula of uniform optimal size, and has corresponding single value curve representation, Compared to the problem proposed pyramid horn antenna design generally comes into operation for a given wavelength into the direction of the coefficient G, the main lobe width equal conditions require the design of the directional coefficient reaches the specified value, the maximum phase difference between the caliber does not exceed the specified value, Horn neck and waveguide mouth fit the best speaker size now used in the university antenna textbook design method is to pyramid horn direction coefficient into
