“…In order to show flexibility, the Center Frequencie (CF) of the first passband can be controlled by changing the internal coupling, such as in Ref. [19], and here is by adjusting the parameter ly . Figure 7 shows the simulated S 21 versus parameter ly , illustrating the CF of the first passband moving to lower frequencies when ly increases.…”

A compact dual‐band bandpass filter (BPF) with high selectivity based on 3D printable groove gap waveguide (GGW) for millimeter application is proposed by the authors. Two stacked dual‐mode GGW resonant cavities including TE102 and TE201 are used to realise a compact structure. The dual‐band bandpass response of the GGW BPF is developed from a split‐type coupling topology which produced two transmission zeros (TZs) between the two passbands. In addition, two TZs are generated outside the two passbands after introducing a source‐load coupling, which achieves a higher frequency selectivity. For verification, a prototype is designed, fabricated and measured. The measured results agree well with the simulated ones, which validates the proposal.

“…The split‐type coupling topology in the dual‐mode form effectively reduces the size and design complexity. Although this method in the dual‐mode form has been proposed to design the multiband filter in the previous work of the authors [24], it is the first time to use it in the field of balanced filters.…”

“…As an effective and simple way to realise the dual-band response, splittype topology is gradually studied in Refs. [21][22][23][24]. Split-type coupling topology, as the name implies, inserts several zeros into a broadband to split it into multiple sub-bands.…”

A new design method of the dual‐band balanced bandpass filter (BPF) using multilayer packaging dual‐mode substrate integrated waveguide (SIW) cavities is proposed. Split‐type coupling topology based on dual‐mode resonators is developed for the design. Firstly, a single‐band balanced filter with perturbed metal vias is designed. The TE201 mode and the TE202 mode perturbed by the metal vias can form a passband. Secondly, an additional metal vias perturbed SIW cavity with the same dual‐mode is placed in the lower layer for the bandstop function. A dual‐band balanced BPF with split‐type coupling topology is successfully realised. Compared with the traditional cascaded single‐mode form, the proposed dual‐mode split‐type design has more compact size and can be more easily extended to multi‐passbands. To verify the proposed method, a dual‐band balanced filter operating at 13.3 and 14.2 GHz is designed, fabricated and measured. The designed dual‐band balanced filter has good filtering performance including differential mode passband transmission and common mode rejection. Measured results show good agreements with simulated ones.

“…The in-band return loss in the K-band is better than 22.1 dB and the minimum in-band insertion loss is 0.5 dB. (7) As an important part of RF sensor systems, SIW-based filters have been applied to many fields. The SIW bandpass filters mentioned above have the advantages of wide passband and good out-of-band rejection performance, but they generally suffer from a higher insertion loss.…”

In this work, a millimeter wave (mm-wave) bandpass filter consisting of six resonant cavities for 5G communication is designed on the basis of a substrate-integrated waveguide (SIW). The bandpass characteristics of the SIW filter are achieved through magnetic coupling, which is accomplished by adjusting the size of the openings between neighboring resonant cavities. The measured fractional bandwidth is 3.56% (24.8-25.7 GHz), with an insertion loss of 0.88 dB at the center frequency of 25.25 GHz, and the in-band return loss is better than 12 dB. The simulated results of this filter show excellent agreement with the measured results. It exhibits low loss, simple structure, low cost, ease of integration with other electromagnetic systems, including sensor systems, and suitability for use in 5G mm-wave bands.
