This project presents the design and simulation of a substrate integrated waveguide band-pass filter for K- Band(12-18 GHz), Ku-Band(18-24 GHz).Band-pass filter is used to receive the desired band of frequencies and to reject the frequencies which is outside the band. Microwave system is generally designed by using fundamental components such as filters, couplers dividers etc. Microstrip based devices can be used upto certain frequencies. The conventional microwave components which are heavy , bulky in size, high cost. In order to overcome these drawbacks we have choosen the substrate integrated waveguide as an approach. The filter is designed on Rogers RT/Duriod 5880 substrate with Ꜫ r=2.2, h=0.508 mm. The metallic via-holes have d=1 mm and p=1.6 mm.
