Network oriented modeling of passive microwave multiports provides a useful representation of the linear device and leads to the reduction of the required computer time and memory capacity for the synthesis procedure. The Brune's multiport method allows to represent the microwave structure in the predefined frequency band as a combination of the lossless connection ideal transformers network and lossy lumped elements with a minimum number of reactive elements. The system identification procedure defines the order of the lumped elements model and the positions of poles and zeros in the complex frequency plane. The simulation of the scattering parameters for the two-port formed by two coupled folded mm-wave antennas for automotive radar applications shows a good agreement with the corresponding measurements.     «
