A multi‐layer interleaved folded half‐mode substrate integrated waveguide (HMSIW) dual‐band filter is proposed. The TE101 and TE102 mode of the HMSIW resonators form dual‐band response by vertical coupling, and the bandwidth of the two passbands can be independently designed by adjusting the coupling apertures. Moreover, three transmission zeros (TZs) are obtained to improve out‐of‐band rejection, and the TZs can be flexibly designed below or above the passband. By vertically superimposing the HMSIW cavity, the HMSIW filter can be extended to multi‐pole dual‐band filters. A dual‐band filter with centre frequency of 3.05 and 4.7 GHz was fabricated and measured to verify the proposed method. The simulated and measured results are in good agreement.

“…Half‐mode substrate integrated waveguide (HMSIW) is one of the miniaturization technique, and it maintains the merits of SIW 14 . Many single BPFs and dual‐band BPFs are developed using single‐mode HMSIW 15,16 . In Reference 17, a novel compact DBBPF is developed using dual‐mode HMSIW cavity.…”

A novel half‐mode substrate integrated waveguide (HMSIW) based dual‐band bandpass filter (DBBPF) is proposed. Back to back connected two defected ground structure (DGS) resonators on the top layer of HMSIW cavity constitute the passband with two transmission zeros (TZs) at a lower frequency. The higher modes TE301 and TE302 of HMSIW cavity give the passband response at higher frequency using the mode shifting technique with slot perturbation. The source‐load coupling has been used to create finite frequency TZs to improve the selectivity of the second passband. Therefore, the proposed filter gives two widely separated passbands, center frequencies (CFs) at 5.83 and 18.1 GHz with an attenuation of greater than 10 dB between the passbands. The synthesized filter is fabricated using a low‐cost single layer PCB process, and the measured S‐parameters are almost mimic the EM‐simulation results.

“…Numerous techniques have been investigated and developed to implement advanced SIW dual‐band BPFs, including the parallel connecting method, the dual‐mode resonator method, and the renowned coupling matrix synthesis design methods . These methods, however, are usually difficult to be transplanted to implement SIW multiband filters according to the authors’ knowledge.…”

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.
