“…With the rapid development of miniaturized and high performance devices in modern wireless communication systems, substrate integrated waveguide (SIW) and half mode substrate integrated waveguide (HMSIW) have emerged as attractive alternatives to implement microwave filters due to their excellent advantages of low loss, high Q-factor, small size and ease of integration with other circuits [1][2][3]. In order to further reduce the sizes of HMSIW devices, complementary split-ring resonators (CSRRs) and complementary spiral resonators (CSRs) are introduced to design HMSIW bandpass filters (BPFs).…”

Abstract-A compact wideband bandpass filter (BPF) based on half-mode substrate integrated waveguide (HMSIW) is proposed in this paper. The proposed BPF is achieved by etching a couple of S-shaped complementary spiral resonators (S-CSRs) on the top layer of HMSIW cavity to achieve a wide passband as well as generate two transmission zeros in the vicinity of the passband respectively to improve the selectivity. In addition, compared with a conventional CSRs-loaded HMSIW structure, the proposed S-CSRs-loaded HMSIW makes the overall size of the filter largely reduced with the same electrical length. Among the HMSIW structures ever reported, the proposed S-CSRs are the first time to be introduced into HMSIW. To validate its practicability, a compact wideband HMSIW BPF loaded with S-SCRs has been designed and implemented through the PCB process. The measured and simulated S-parameters of the filter are presented to show the proposed filter's predicted performance, and good agreements is obtained between them. This result demonstrates that the newly proposed HMSIW structure loaded with S-CSRs is an excellent candidate for compact filters.

“…When designed carefully, diplexers based on stepped impedance resonators provide much better isolation due to equal velocities division in even and odd mode waves [3,4,8]. Lately, increased attention has been paid to realize new filters by combining complementary split ring resonators (CSRRs) and substrate integrated waveguide (SIW) structures [2,6,7]. SIW is a guided wave structure synthesized by metallic vias on a planar substrate with several advantages in terms of high quality factor, power handling capability, and low loss.…”

Abstract-In this letter, we present a diplexer implemented on a substrate integrated waveguide (SIW) with stepped impedance complementary S-shaped resonators (CSSRs). The variable frequency response of the stepped impedance concept adjoining SIW technology leads to improved device performance in terms of matching and isolation. Simulated and measured results show input matching, |S 11 |, better than −15 dB and output isolation, |S 32 |, below −30 dB for the frequency range 1-4 GHz. Furthermore, CSSRs offer a degree of freedom to design fundamental and higher order frequencies by selectively tuning the geometrical parameters. This simple yet effective approach eliminates the complexity to design diplexers based on complementary split ring resonator (CSRRs).

“…It was further extensively studied by Dong et al in [19]. CSRR is also used to the design of HMSIW bandpass filter [20] with sharp rejection skirt and SIW diplexer [21]. In [22], the coupling effect between CSRR and SIW cavity is used to reduce the resonance frequency of a conventional SIW cavity.…”

Abstract-A novel quarter-mode substrate integrated waveguide (QMSIW) resonator with back-to-back triangular complementary split-ring resonators (CSRRs) etched on the waveguide surface is proposed in this paper. The proposed CSRR structures allow the implementation of a forward-wave passband propagating with high selectivity below the characteristic cutoff frequency of the conventional QMSIW. Utilizing the property of flexible open structure on QMSIWs' two sides, a cascaded quadruplet (CQ) bandpass filter (BPF) using the proposed QMSIW resonator and proximity coupling structure is presented. Compared with some other reported BPFs with SIW technique, the presented BPF using the novel QMSIW resonator has great improvements on size reduction and selectivity, simultaneously, with simple geometry. At the center frequency of 3.7 GHz, the designed BPF filter achieves a wideband with a fractional bandwidth up to 24.3% and a high selectivity with a shape factor of 1.23. The compact dimension of this filter is as small as 0.36λ g × 0.36λ g , where λ g is the guide wavelength at the center frequency. The proposed filter is simulated, fabricated and tested. The measured results are in good agreement with the simulation.
