“…The fabricated bandpass filters with some previous Microstrip-SIW, SIW, Complementary Split Ring Resonators (CSRRs)-SIW, and Spoof Surface Plasmon Polaritons (SSPPs)-SIW are compared with measured performance and type of design in Table V. It is shown that the bandpass filters in [21] and [25] have a very wide passband. The filters in "this work" and [18] have approximately the same "insertion loss" (IL) and "return loss" (RL).…”

In this paper, the Microstrip-Substrate Integrated Waveguide (M-SIW) bandpass filter is designed, simulated, and fabricated based on the theoretical analysis. The Substrate Integrated Waveguide (SIW) highpass filter and the microstrip lowpass filter are combined in a hybrid design to achieve the M-SIW bandpass filter in the X-band. This design is more comprehensible and easier to achieve a bandpass filter at a desired frequency. The SIW highpass filter and the microstrip lowpass filter are connected in series to achieve the bandpass filter. To the measured results of the fabricated M-SIW bandpass filter, the center frequency is 10.20 GHz and the bandwidth is 2.40 GHz. When the analytical and measurement results are compared, the frequency change in the cut-off frequency is 6.02 % and the frequency change in the bandwidth is 8.74 %. It is generally seen that analytical, simulation, and measurement results are compatible with each other. The M-SIW bandpass filter can be broadly used in radar, Worldwide Interoperability for Microwave Access (WiMAX), and satellite technologies. The filters are simulated in Computer Simulation Technology (CST) Studio Suite.

“…A broadband BPF using hybrid SSPP‐SIW structure has been proposed in [29], which showed wide out‐of‐band rejection, and dispersion analysis of SIW and SSPP units are carried out in [31]. Recently, a bandpass filter based on half‐mode SIW and double‐layer SSPPs has been developed [30], which features wider BW, smaller size and lower loss than previously reported structures.…”

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.

“…Researchers have spurred a long-held interest to design electromagnetic structures based on SSPs concept in microwave and terahertz frequency regions. To generate SSPPs mode, SSPPs can be integrated through mode convertors to the conventional microwave or terahertz components, for instance, microstrip TL, coplanar wave guide (CPW-line), and substrate integrated waveguides (SIWs) 10 , 11 , or half-mode SIWs 12 . SSPPs has a very wide applications such as high efficiency SSPPs TL 13 – 17 , 3D SSPPs waveguides including one side L-shaped unit cells 18 , SSPPs antennas 19 – 21 , splitters 22 , and filters 23 – 29 .…”

This paper presents a novel and compact band-pass filter based on spoof surface plasmon polaritons (SSPPs) concept for 5G applications. In the first place, an SSPPs unit cell including L-shaped grooves and its equivalent circuit model are introduced. The obtained results from dispersion analysis shows that cut-off frequency of the cell can be considerably decreased thanks to its geometrical configuration. In the second place, a miniaturized SSPP transmission line (TL) consisting of the proposed unit cell with cut-off frequency of 29.5 GHz is designed. Two mode convertors have been employed for efficient connection between coplanar waveguides and SSPP TL. Moreover, a new method based on loading one unit cell of SSPP TL by stub resonators is proposed in order to block a specific frequency band. An equivalent circuit model for the cell with the resonators is proposed to predict rejected frequency range. Thereafter, as an example of our method, a SSPPs filter operating at 26.5–29.5 GHZ is designed by means of connecting stub resonators with different lengths to provide close resonance frequencies. The circuit model, full wave simulation, and measurement results are in a good agreement. The results of proposed groundless SSPP TL and filter structures are promising to make groundless 5G applications possible.
