An efficient analysis of microstrip trisection filters using an iterative method combined by approach Multi-scale

This paper presents an efficient execution of the Wave Concept Iterative Procedure algorithm (WCIP) combined with the Multi-scale approach´s module (M.WCIP). This approach is introduced to solve the problem of the relationship between circuit complexity and computation time. Therefore, this work consists of a development of simulation software based on this combination for planar circuits very jagged structure´s simulation. The two layouts of the micro-strip trisection filter´s simulation are made. The first layout has a higher selectivity on the high side of the pass-band and the second has a higher selectivity but on the low side of the pass-band. The results obtained the WCIP and M.WCIP are analyzed and validated by comparison with results obtained by other researchers.
