| 摘 要： | 文章分析了波导-带状线通过小孔耦合的传输特性,通过保角变换求出带状线中的场分布,利用小孔衍射理论得到波导-带状线间的耦合度的表达式,并且理论计算值与测量值吻合较好.通过数值分析,结果表明:耦合小孔半径和厚度对耦合度的影响比较大,传输线的工作频带比较宽.

| Abstract: | An analysis of transfer characteristic of coupling between a stripline and a rectangular waveguide is presented.The field distribution in the stripline is obtained by the conformal transformation function.The expression for the coupling coefficient by the diffraction theory of small coupled holes is derived.The theoretical results show good agreement with the experimental results.The conclusion is obtained by the numerical analysis: The radius and depth of coupled hole have a big role to the coupling coeffi... |
