Abstract
Conventionally, we have to know the value of at least one terminator in advance when measuring multi-port network by using two-port vector network analyzer. [16] proposed the algorithm for three-port to two-port port reduction method with unknown terminators. [17] proposed the algorithm which can reconstruct the multi-port network with known terminator from three-port or more port scattering matrices. This work adopt the main idea of these two works and implement with Matlab program. The measured scattering matrices of a branch line coupler on FR4 substrate using proposed port reduction method shows good agreement with measurement by multi-port VNA.
