“…1 At present, substrate integrate waveguide (SIW) technology has gradually been widely used in designing filtering crossovers owing to the merits of low cost, high Q factor and easy integration. [2][3][4][5][6] Nevertheless, the filter transmission responses of the reported SIW crossovers are concentrated in single passband. Until now, to the best of authors' knowledge, there has been no multi-band SIW filtering crossovers been reported, and thus, it is eager to implement the SIW multi-band filtering crossovers for multi-band communication system applications.…”

A compact filtering crossover utilizing substrate integrated waveguide (SIW) quintuple-mode resonator (QMR) technology is proposed for the first time. Benefiting from this technology, the proposed crossover firstly breaks the status quo that SIW crossover filtering response is only concentrated in single passband, thereby extending the applications of the SIW crossovers. In design, the QMR is derived by embedding metal-via holes in the conventional SIW resonant cavity, thus to produce quintuple resonant modes featuring with specific electric distributions. Next, by dividing these modes into two groups, a triple-mode bandpass filter (BPF) channel and a single-mode dualband BPF channel are both realized. To implement two flat passband channels, there are two SIW cavities cascaded. And also, the isolation between two channels is implemented by employing the orthogonal characteristic. In this way, a crossover is implemented. The proposed design method can be a good candidate for developing SIW multi-band filtering crossovers. For verification, an example circuit has been designed, fabricated, and measured.

“…Besides the above-mentioned dual-band BPFs, a three-state SIW diplexer with flexibly controlled CFs was proposed and reported in [129] with three input/output ports fed at specific positions of a single cavity operating with quadruple modes of TE 102 /TE 201 /TE 103 /TE 202 based on this kind of scheme. Additionally, a higher-order SIW diplexer was also developed and presented in [130] based on a single slots-perturbed quadruple-mode cavity, as the last circuit prototype shown in Fig. 14.…”

Multiband bandpass filters (BPFs) and multiplexers are essential front-end modules in the development of multifunction, multistandard, and multiband wireless communication, sensing, and positioning systems that are required in current and future intelligent electronics applications. In this paper, numerous implementation schemes and topologies of multiband BPFs and multiplexers, which have been proposed, studied, and developed so far, are holistically summarized and elaborated in terms of their merits and drawbacks. Subsequently, various technical approaches and diverse design methodologies based on substrate integrated waveguide (SIW) technology are thoroughly examined and reviewed with respect to technical features, electrical performances, and practical applications. Finally, future research and development directions and prospects of SIW multiband BPFs and multiplexers are briefly unraveled.

“…For this reason, the researchers have suggested the use of orthogonal dual modes TE 201 and TE 102 of the SIW cavity to achieve different passband transmission by making the resonant frequency inconsistent through a reasonable design 18,19 . Multiple different TE modes are used, 20 which can significantly increase the frequency ratio of the two passbands. Additionally, the three‐dimensional (3D) structure based on three orthogonal modes TM 101x , TM 101y , and TM 101z allow for transmissions within three different channels 21,22 .…”

SummaryThis paper proposes a high‐selective crossover with a third‐order filtering characteristic, high passband isolation, and multiple controllable transmission zeros based on a coupled topology using single‐ and dual‐mode resonators. By virtue of the odd‐ and even‐mode feature of the stub‐loaded dual‐mode ring resonator, not only can the two resonant modes for different passbands be relatively independently controlled, but also better isolation can be achieved. With a single‐mode resonator and stub‐loaded dual‐mode resonant coupling topology, the resultant crossover can perform third‐order filtering performance in two distinct passbands/channels and generate several transmission zeros outside the desired bands to improve the isolation between the passbands. Experimental results demonstrate that, compared with conventional works, the filtering order of the proposed crossover is promoted and its passband isolation can be significantly improved by about 8 dB. The proposed work may facilitate its widespread applications in high‐performance multichannel integrated microwave systems for avoiding interference between multiple intersecting signal paths.
