摘要
为了研究同轴口面的辐射特性,从同轴口面的电磁场的矢量模函数出发,应用口面场的傅里叶变换求解同轴口面的辐射场,研究了同轴区域的电尺寸、同轴喇叭张角与2个常用的高次模辐射特性之间的关系,给出了2个常用模式的比例与辐射方向图的关系和供工程设计用的参考数据。
To study the radiation characteristics of coaxial aperture,the coaxial aperture radiation field is calculated by Fourier transform based on the vector mode function of aperture field.The relationship between the radiation characteristics of two common highorder modes and the electrical size of coaxial area and the coaxial horn angle is studied.The relationship between the aperture ratio and radiation pattern for the two common modes is presented,and the reference data for engineering design is given.
