A wave digital approach in obtaining z-domain functions for microstrip stub-line structures

An efficient method based on transfer parameter approach is proposed to obtain the scattering parameters in z-domain of planar microstrip stub-line structures. A wave digital network (WDN) which represents a digital model of a microstrip stub-line structure is observed here. WDN is composed of cascaded unit elements and three-port adaptors. An open T-resonator realized in microstrip technique, proving the response accuracy of the new technique, is given.
