Dual-Band Substrate Integrated Waveguide Filter With Independent TE<sub>101</sub> and TE<sub>102</sub> Coupling
Bibliographic record
Abstract
This article presents a technique for dual-band substrate integrated waveguide (SIW) filters to implement independent coupling for their dual bands based on multilayers and overlapped cavities. It is achieved by using the proposed intercoupling slots in the middle layers. The slots parallel to and near the edge implement TE101 coupling, while the orthogonal slots in the center implement TE102 coupling, and they work independently of each other. Due to their independence, the design complexity of dual-band SIW filters could be significantly decreased, particularly for high-order applications, and the design flexibility could be significantly increased, allowing the use of additional techniques to produce distinct and high-performance responses. Five prototypes are provided, including those that additionally use cross coupling and spurious mode suppression to achieve significantly improved selectivity. The proposed technique should be efficient for developing high-performance dual-band SIW filters in microwave and wireless circuits and systems.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
