Microwave interdigital bandpass filters modeling Available to Purchase

An improved model for microwave interdigital filters design and analysis is developed by correction of Denig’s procedure (1989). This model enables correct modeling multiple‐coupled transmission line structures as parallel sections of single coupled lines. Also, it is very suitable for the design and analysis of the filters by means of widely used microwave CAD programs. In this way the design and analysis of the microwave interdigital filters are significantly simplified. The verification of modified Denig’s procedure is carried out through the two examples of the microstrip interdigital bandpass filters by means of program package LIBRA.
