Wave-based Modeling and Analysis of Microstrip Stub-line Structures (original) (raw)

The purpose of this paper is to show that the one-dimensional (1D) wave digital approach is suitable for modeling and analysis of stub-line structures. A stub-line structure, divided into uniform sections, can be efficiently modeled by wave digital network (WDN). Frequency response in WDN is obtained by direct analysis of formed block-based network. In the other hand, response can be calculated in the frequency or in the time domain directly from known network function in z-domain. The open T- resonator circuit, proving the response accuracy of the new technique, is given.
