摘　　要：从电磁场理论出发,研究印刷电路板上耦合传输线信道传输矩阵(CTL-CTM)的建立。根据耦合传输线的串扰模型,基于有限元法建立CTL-CTM。利用HFSS软件仿真建立的信道传输矩阵元素,与从电路角度建立的信道传输矩阵元素进行对比,结果表明两者基本一致,验证了从电路角度建立CTL-CTM的准确性和可行性,为基于CTL-CTM进行串扰减小方法的研究奠定了基础。Proceeding from the electromagnetic field theory,the establishment of coupled transmission lines-channel transmission matrix(CTL-CTM)on printed circuit board is studied.In accordance with the crosstalk model of the coupled transmission lines,the CTL-CTM is established on the basis of finite element method.The elements in the established channel transmission matrix are simulated by means of HFSS software,and compared with the elements in channel transmission matrix established in relying on circuit.The results show that the crosstalk curves of the two methods are basically the same,which verifies the accuracy and feasibility of CTL-CTM established in relying on circuit,and lays a foundation for the research of crosstalk reduction method based on CTL-CTM.
