“…As discussed in [1,2], the characteristic cutoff frequency of the SIW is mainly controlled by its width a in Figure 1. A SIW with a and h, the height of the substrate, can be equivalent to a conventional rectangular waveguide with the same height, h, and width, a EFF SIW , which is shown as…”

“…Substrate integrated waveguide (SIW), early introduced by Wu et al, has attracted plenty of attention and utilized in different applications due to its merits of higher quality factor, easy integration, low cost, high power handling and mass production [1][2][3][4][5]. The half-mode substrate integrated waveguide (HMSIW) has been developed for microwave and millimeter wave applications [6,7].…”

Abstract-In this paper, a X-band wideband bandpass filter based on a novel substrate integrated waveguide-to-defected ground structure (SIW-DGS) cell is presented. In the cell, the DGS is etched on the top plane of the SIW with high accuracy, so that the performance of the filter can be kept as good as possible. Finally, the filter, consisting of three cascaded cells, is designed and measured to meet compact size, low insertion loss, good return loss as well as smooth group delay. There is good agreement between the measurement and simulation results.

“…The most common technique is to form the SIW cavity through metallic sidewalls [10] as shown in Figure 1(a). A dielectric substrate having width of h forms the resonator, and the resonator is of length L. The bottom and top of the resonator are constructed through placing metallic plates and conducting posts/vias going through the substrate connects the top and bottom plates, hence forming the sidewalls of the cavity.…”

Abstract-A tunable planar bandpass filter based on a technique that utilizes a half mode substrate integrated waveguide (HMSIW) and novel inter-resonator coupling is presented. The tunable HMSIW based bandpass filter is implemented using two half triangle shaped cavities coupled together through inter-resonator coupling forming half mode bowtie shaped structure. The bowtie-shaped filter exhibits similar performance as found in rectangle-and circle-shaped SIW based bandpass filters. This concept reduces the circuit foot print, and miniaturization high quality factor is maintained by the structure. The tunable filter utilizes packaged RF MEMS switches; switching between different configurations of switches achieves four distinctive frequency states between 4.8-5.3 GHz. The filter maintains a constant absolute 1 dB bandwidth of 100 ± 10 MHz for all frequency states.

“…The emerging substrate integrated waveguide (SIW) technique has been proven to be effective in the integration of planar and nonplanar circuits by using easy and low-cost standard PCB or LTCC fabrication process [1,2]. Then, the traditional non-planar hollow rectangular waveguide can effectively be synthesized into planar substrate with metalized slots or trenches or even arrays of metallic via posts.…”

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.
