Abstract

This paper presents a design and implementation of rectangular waveguide filters by using the simulation tools. The waveguide filters are designed by using numerical analysis based on the Wave Iterative Method (WIM) called WFD (Waveguide Filters Design). This simulation program can analyze the electrical network of inductive filter. The sample rectangular waveguide filters is designed on structure consisting of three circuits as a simple band pass filter, filter with two inductive irises and three inductive irises in cascade. We determinate the operating frequency equal to 4.0-4.8 GHz approximation. Then the inductive waveguide filters were implemented by using an aluminum material. The analyzed results of inductive iris by WFD agree well with results of CST Microwave Studio^®. Finally the measured results of sample waveguide filters are consistent with the simulation tools.
