| Abstract(in English) | A measurement method for the S-parameters of a multiport reciprocal circuit is reported where the majority of the ports (indirect-measured ports) are connected with some known loads and the remaining ports are directly measured by changing the load values. First, some of the indirect-measured ports are terminated with loads to temporarily exclude them from the measurements so that the number of indirect-measured ports equals to that of direct-measured ports. Then, our previously proposed method for a circuit in which the majority of ports are directly measured is applied to estimate the partial S-matrix. It is treated as if directly measured and the process is recursively repeated until no ports need to be excluded. A numerical experiment with a simple PCB is shown to evaluate the validity and the robustness of this method. |
