研究了不接地共面波导截面参数的不确定性对特性阻抗和传播常数的影响。对于我们的计算，准TEM模型，考虑到非理想导体，衬底损耗和有限的金属化厚度的影响。传播的不确定性进行了研究与蒙特卡洛（MC）模拟的帮助。通过两种典型的微波基板（AF 45和Al 2O3）来举例说明不同制造技术的效果。此外，在输入量的不确定性的影响进行了调查，这样的方式，可以得出的结论的设计CPWs以及材料测量方法的精度要求。
We investigate the effect of uncertainties in the cross- sectional parameters of ungrounded coplanar waveguides (CPWs) on the characteristic impedance and the propagation constant. For our calculations, a quasi-TEM model is used that takes into consideration the effects of non-ideal conductors, substrate loss and finite metallization thickness. The propagation of uncertainties is studied with the aid of Monte Carlo (MC) simulations. The effect of different manufacturing technologies is exemplified by two typical microwave substrates (AF45 and AI2O3). Furthermore, the impact of the uncertainties in the input quantities is investigated in such a way that conclusions for the design of CPWs as well as for the requirements on the accuracy of material measurement methods can be drawn.
