“…Numerous techniques have been investigated and developed to implement advanced SIW dual-band BPFs, including the parallel connecting method, 1 the dual-mode resonator method, [2][3][4][5][6][7][8][9][10][11] and the renowned coupling matrix synthesis design methods. [12][13][14] These methods, however, are usually difficult to be transplanted to implement SIW multiband filters according to the authors' knowledge. Only few solutions can be found for SIW triple-band BPFs 12,[15][16][17][18][19] and a quad-band one, 19 and no solution has been reported so far for SIW more band BPFs due to the difficulties in simultaneously controlling the frequencies and the couplings of multiple passbands, rendering the great necessity to develop novel realization methods for SIW multiband filters.…”

Substrate‐integrated waveguide (SIW) sext‐band bandpass filter (BPF) composed of two dual‐mode cavities coupled with multiple single‐mode ones is synthesized and designed for the first time by combining split‐type triple‐band symmetrical frequency responses for two virtual wide passbands dominated by TE101 and TE201 modes in SIW rectangular cavities. By applying our previously proposed dual‐mode frequency and coupling controlling techniques, the center frequencies and fractional bandwidths of the two virtual passbands can be allocated flexibly. An experimental prototype with the two virtual wide bands centered at 11.993 and 14.336 GHz is synthesized, designed, fabricated, and tested to demonstrate and validate the collaborative design concept, showing excellent agreement between the measured and simulation results.

“…However, their sizes are still large. In [11], the authors proposed a new method to design compact balanced filters based on quarter-mode SIW (QMSIW) and eighth-mode SIW (EMSIW) cavities. The designed filters have compact sizes for size-reduced QMSIW/EMSIW cavities.…”

“…The designed filters have compact sizes for size-reduced QMSIW/EMSIW cavities. However, the first designed balanced SIW filter in [11] has poor selectivity because no transmission zero (TZ) is close to the differential-mode (DM) passband. The second designed balanced SIW filter has good selectivity due to the quasi-elliptic response [11].…”

This letter proposes a compact single-layer balanced bandpass filter (BPF), which is realized by a new arrangement of eighth-mode substrate integrated waveguide (EMSIW) cavities. Under differential-mode (DM) operation, the half bisection topology of the proposed EMSIW filter can be equivalent to a quadruplet scheme based on four coupled EMSIW cavities. The negative cross coupling can be easily realized by the nature of the fringe electric fields of opened ends of EMSIW cavities. For the demonstration, a balanced EMSIW filter with the operating frequency at 2.4 GHz is designed, fabricated, and measured.

“…In [4], a new type of HMSIW periodically loaded with different lumped elements and structures was proposed [5] which presented a systematic investigation of SIW filters from a thorough analysis of the quarter-mode SIW cavity. In [6], a dual-band bandpass filter using EMSIW resonators was proposed. A novel sixteenth-mode substrate integrated waveguide (SMSIW) bandpass filter loaded with complementary split-ring resonator (CSRR) was introduced in [7].…”

Abstract-This paper presents two novel bandpass filters using sixteenth mode substrate integrated waveguide (SMSIW) and thirty-second mode SIW (TMSIW) cavities, respectively. The overall size of SMSIW and TMSIW cavities can be reduced by a factor of 15/16 and 31/32 in comparison to the filters designed in the conventional SIW resonator, while keeping almost the same resonant frequency. Based on SMSIW cavity, a first-order filter with the center frequency of 2.45 GHz and a transmission zero (TZ) located at the upper-stopband is proposed. The second-order TMSIW cavity filter exhibits one TZ at the lower-stopband and two TZs at the upper-stopband, and it has a better performance of the passband than the former with the same size and center frequency. It also has a wider upper-stopband with suppression of an unwanted harmonic at 7.6 GHz. Two intersecting rectangular slots are etched between the two cavities with a smaller angle between them of 30 degrees. The whole size of the filter is 24.2 mm × 29.1 mm × 0.508 mm. The filters are fabricated in SIW technology, and the frequency response shows good agreement between simulated and measured results.
