摘　　要：在研究传输线时,当传输线的几何尺寸l与工作频率所对应的波长λ可相比拟时,传输线就要用分布参数电路来讨论,在研究分布参数电路时,可以应用电磁场理论,也可以采用电路理论,采用后者,用等效的方法将耦合微带传输线等效为分布参数电路模型,然后用基尔霍夫定律求出其传输线方程。While studying transmission lines, as geometry size of transmission line and corresponding wavelength of operating frequency can Analogy, discuss transmission line with distribute parameter circuit, while studying distributed parameter circuit, can use the theory of electric magnetic field, can adopt the theory of the circuit too. This article uses the next, transmission of the coupled microstrip line equivalent the circuit model of distributed the parameter by equivalent means, then with Kirchhoff＇s law asked out transmission line equation.

关 键 词：耦合微带线 等效 分布参数 传输线方程
