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.<\/jats:p>","DOI":"10.12720\/jcm.16.12.553-558","type":"journal-article","created":{"date-parts":[[2021,11,24]],"date-time":"2021-11-24T03:19:49Z","timestamp":1637723989000},"page":"553-558","source":"Crossref","is-referenced-by-count":3,"title":["Designing of Novel Eighth-Mode Forth-Order Substrate Integrated Waveguide Band-Pass Filter with High Selectivity"],"prefix":"10.12720","author":[{"name":"Department of Electronic Engineering, Howard College, University of KwaZulu-Natal, Durban - 4041, South Africa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cleophas D.
