Designing of Novel Eighth-Mode Forth-Order Substrate Integrated Waveguide Band-Pass Filter with High Selectivity

Abstract
—A fourth-order Substrate Integrated Waveguide (SIW) filter has been presented in this research work. The four Eighth-Mode (EM) SIW cavity resonators have been electrically coupled and source to load coupling has been achieved by a slight modification of the eighth-mode resonator cavity. Here a 87.5% size reduction has been achieved using the EMSIW, which plays a significant role in achieving miniaturized structure. The operating center frequency is 13.5 GHz with a 3dB bandwidth of 0.5 GHz. The Rogers-5880 substrate has been utilized with relative permittivity of 2.2. The results show that the filter has three transmission zeros on either side of the pass-band, which gives high selectivity and a high out of band rejection.
