Abstract :
A microstrip interdigital filter has been analyzed using the 3-D transmission line matrix (TLM) method. The effect of via holes used for grounding the quarter-wave resonators is studied by discretizing them along with the rest of the circuit. The resonant frequencies of the modes excited in the resonators are identified using Prony´s method
