本文介绍两种用于TI-59型可编程序计算器的程序。用第一个程序可在已知衬底材料的ε_r、w/h时计算微带线的特性阻抗Z和(ε_e)~(1/2),亦可在已知ε_r、Z时计算w/h、(ε_e)~(1/2),还可自动、连续计算具有任何ε_r介质的微带线参数数组。用第二个程序能在已知二端网络输入端电压反射系数时计算其输入阻抗。 This article describes two programs for the TI-59 Programmable Calculator. Using the first program, we can calculate the characteristic impedance Z and (ε_e) ~ (1/2) of the microstrip line when the substrate material ε_r, w / h is known, and calculate w / h, (ε_e) ~ (1/2), the array of microstrip parameters with any ε_r medium can also be automatically and continuously calculated. The second procedure calculates the input impedance when the voltage reflection coefficient of the two-terminal network input is known.
