“…Moreover, it has extremely low rates of atmospheric attenuation in comparison to frequencies above 10 GHz, which makes this band suitable for the harshest weather conditions [28]. Although different types of SIW filters can be found in the literature [29][30][31][32][33][34][35][36][37][38][39][40], the design procedures are not given properly or are suited only for a specific filter order. This work discusses the design procedures of two different types of SIW BPFs in details; in particular the centered post and the iris types.…”

The substrate integrated waveguide (SIW) has been proposed as a reliable alternative to the rectangular waveguide due to its small size, low cost, high performance, ease of manufacturing and simplicity of integration with other microwave components. This paper focuses on SIW band-pass filters and presents their design procedure in details. The methodology is applied to post and iris SIW filters working at X-band with different orders, responses and bandwidths. Two prototypes of third-order post and iris SIW filters are fabricated and measured with a vector network analyzer. The filters are designed to work at 10 GHz center frequency and 500 MHz bandwidth. The simulation results and measurement results of the post and iris SIW filters are compared. In the simulations lower than 0.9 dB insertion loss and better than 20 dB return loss is observed in the pass-band of the filters. The post filter exhibits lower insertion loss and higher reflection loss at the stop-band of the filter. With their low cost, small size, ease of manufacturing, high performance and integrability with other components, both of the demonstrated X-band SIW filters are very versatile and well suited for a variety of market applications, including radars and satellite communications.

“…Because of these inherent properties, SIW filters are adapted as promising candidates for microwave and millimetre‐wave systems. The traditional SIW filters often suffer with narrow passband and poor stopband attenuation [17–19]. There are some efforts have been made in [20–23], to broaden the passband bandwidth (BW) of SIW filters.…”

Two bandpass filters based on hybrid spoof surface plasmon polariton (SSPP) and substrate integrated waveguide (SIW) are presented for X-band applications, herein. The dispersion and transmission characteristics of the proposed hybrid SSPP-SIW structures are analysed, and the influence on the variation of their structural parameters is investigated. The proposed dumbbell-shaped SSPP shows more slow-wave effects than the rectangle-shaped SSPP for the same height of grooves, and hence could be a good choice in the design of compact, low loss and highly integrated microwave and terahertz devices. The lower and upper cutoff frequencies of hybrid SSPP-SIW bandpass filters can be adjusted independently by varying the structural parameters of SIW and SSPP units, respectively. The proposed two filters exhibit excellent passband (8-13.15 GHz for filter I and 8-13.5 GHz for filter II) and wide upper-band rejection (>42.5 dB from 14.1 to 20 GHz for filter I and >41 dB from 14.2 to 19.5 GHz for filter II) simultaneously. Their size is very compact, amounts to only about 1λ g � 0.7λ g , where λ g is the guided wavelength in the SIW at the centre frequency.
