Simulation and Analysis of Edge-Coupled Band Pass Filter for Ku Band Application

In this paper, an edge-coupled microstrip band pass filter using Ansoft designer is proposed. The filter is operated at Satellite downlink frequency for 12.2-12.7 GHz & the filter is designed on Roger RO6006 substrate with dielectric constant of 6.45, with dimension conductor thickness 0.035 mm and substrate height 0.787 mm. The proposed filter is designed at a center frequency of 12.45 GHz. In this paper, third order band pass filter development with the assistance of the Richards-Kuroda Transformation method is used. A comparison with filter designed on stripline technology is also presented
