The need for more accurate modeling of microstrip discontinuity structures has become increasingly apparent with the advent of monolithic microwave integrated circuits (MMICs), as well as the push to higher and higher millimeter-wave frequencies. The proposed research is aimed at tackling this problem through a theoretical and experimental study at the University of Michigan which will be augmented by collaboration with the Torrance Research Center of Hughes Aircraft Company. The proposed theoretical approach involves an accurate computation of the current distribution along the microstrip conductors using the method of moments. Based on the current distribution, a frequency dependent equivalent circuit model is derived for the discontinuity. These numerical results are to be compared with S-parameter measurements using automatic network analyzer equipment in conjunction with an appropriate de-embedding technique in the frequency range from 2 to 40 GHz.

随着单片微波集成电路(MMIC)的出现以及对越来越高的毫米波频率的推动，对微带不连续结构的更准确建模的需求变得越来越明显。拟议的研究旨在通过密歇根大学的理论和实验研究来解决这一问题，该研究将通过与休斯飞机公司的托兰斯研究中心合作加以加强。所提出的理论方法包括使用矩量法精确计算沿微带导线的电流分布。在电流分布的基础上，推导出了不连续性的频率相关等效电路模型。这些数值结果将与使用自动网络分析仪设备结合适当的去嵌入技术在2到40 GHz的频率范围内进行S参数测量进行比较。
