“…However, their narrow passband prevents their use in the modern communication system as 5G. To provide a wide passband, several high order multi-mode resonators have been proposed [5][6][7][8]. In [5], a wideband SIW filter with compact size using a U-shape slot on the metallic plate of a double SIW cavity to produce five resonant modes is investigated.…”

“…Although the proposed fifth-order passband filter provides 42% fractional bandwidth, with only one TZ at the upper frequency side, the filter cannot achieve a good selective response. In [6], a quintuple-mode filter was proposed by modifying a quarter mode substrate integrated waveguide (QMSIW) resonator. This filter provided a sharp selectivity with four TZs.…”

This paper proposes a novel wideband filter based on a quintuple-mode substrate integrated waveguide (SIW) resonator. Two metallic vias loading a rectangular SIW cavity diagonal line are used to excite five resonant modes. A pair of the complementary split ring resonators (CSRRs) etched on the top plane to further control the degenerating modes. A quintuple-mode filter is implemented based on this resonator. One transmission zero (TZ) at the lower frequency side and three TZs at the upper frequency side were obtained to improve the filter selectivity. A seven-order filter with wide stopband rejection is investigated under the use of a pair of microstrip low-pass filters (LPFs). The proposed SIW cavity filter has been designed, manufactured, and measured as an experimental example to verify the proposed concept. Simulation and measurement results agree with 49.8% of fractional bandwidth at 5.3 GHz central frequency.

“…Recently, the multiple-mode resonator (MMR) approach becomes an important key to reduce the filter size and to improve the filtering performance, which was firstly proposed by [1]. Various research studies on multi-mode filters based on different configurations have been done to extend the filtering bandwidth [2][3][4][5][6][7][8][9]. The multiple-mode stub-loaded resonators in [2,3] exhibit good wideband performances with a very compact size.…”

This paper presents a novel quintuple-mode wideband filter based on a circular Substrate Integrated Waveguide (SIW) cavity. To implement this filter, a pair of two metallic perturbation vias loaded around the diameter resonator line is used. An Elliptic Dielectric Resonator (EDR) was introduced in the middle of the cavity to shift certain resonant modes and restrain the higher-order modes. The optimal dimensions and dielectric permittivity of the EDR are investigated. A single SIW resonator filter has been designed, manufactured, and measured as an experimental example to verify the proposed design. Simulation and measurement results agree with 51.7% of fractional bandwidth at 10.1 GHz central frequency, with one transmission zero (TZ) at the lower frequency side and four TZs at the upper side.

A compact triple‐mode (TM) bandpass filter (BPF) is designed based on the proposed dual capacitively‐loaded (DCL) substrate‐integrated waveguide (SIW) resonator. Two identical T‐shaped grounded striplines are inserted into a square SIW cavity to generate a capacitively loading effect without damaging cavity surface integrity, which contributes to maintaining EM‐shielding capability. By adjusting the size and position of the DCL structure, the first three resonant modes, including TE101, TE201, and TE301 are easily controlled to design a TM‐BPF. A transmission zero (TZ) is introduced by the grounded striplines and flexibly controlled. TZ is tuned to suppress the TE102 mode to acquire a wide upper rejection band. Furthermore, the filter design procedures are presented in the context under specified filter performance. Finally, to verify the proposed design method, an example of self‐packaged TM‐BPF at 6 GHz with a good lower stopband and a wide upper rejection band is designed, fabricated, and measured. The measured results are in good agreement with simulated ones.
