In this paper, an offset posts K-band bandpass filter has been designed using substrate integrated waveguide (SIW). SIW is formed inside a dielectric material by applying a top metal over the ground plane and trapping the structure on either side with rows of plated vias. SIW is effective and efficient solution in waveguide technique. The slotted windows are cut in tapered transition of SIW filter to attain low loss. The proposed filters are designed at 23 GHz center frequency. The simulated results exhibit low losses and sharp roll off characteristics in pass band. There is good agreement between the simulated results and the experimental results. The proposed filter is suitable for use in microwave communication devices.
