Microstrip disk configuration power divide/combiner modelling using TLM approach

In this paper a new simple procedure for the analysis of disk configuration microstrip structures is given. The procedure is based on the TLM approach, i.e. on domain segmentation and replacing segments with lumped element circuits. An equivalent circuit representing microstrip structure can be easily solved using any standard electrical CAD program. For three types of subsections (INN, CENT, OUT) appearing in the disk configuration power/divider expression for obtaining equivalent circuits parameters are derived.
