The asymmetric stripline is widely used in LTCC microwave integrated circuit system. Different kinds of discontinuity are often encountered in the circuit design, such as open circuits, steps, right-angle bends, T-junctions and so on. This paper successfully transplantes the equivalent circuit model of microstrip line discontinuity to the asymmetric stripline so as to deal with T-junction discontinuity and the branch-line coupler constructed by parts with various discontinuity. Compared with numerical results, the average error of S parameters is less than 2%.

偏心带状线广泛应用于LTCC微波集成电路系统中，其电路设计过程中也经常会遇到诸如开路端、阶梯、直角拐角及T型接头等各种不连续性问题；该文成功地将原有的微带线不连续性等效电路模型移植到偏心带状线上，从而分析了其T型接头不连续性和由其不连续性部分组成的电路组件分支线耦合器；与数值计算结果相比，其S参量的平均误差小于2%。
