摘要
利用一种简单的保角变换函数求出了带状线中的场分布,从而提出了波导一带状线-同轴线型定向耦合器的一种设计方法,导出了耦合度、方向性、理想方向性夹角等有关公式,并对理论计算结果与实际测试数据进行了对比,两者得到满意的吻合。
The distibutrion of electromagnetic field in stripline is obtained by a simple eonformal transformation and a design method of waveguide stripline coaxial line directional coupler is presented in this paper. The formulas of coupling coefficient, directivity and ideal directivity angle are derived. The measured datum are in good agreement with the calculated results.
