A Broadband Microstrip-to-Folded Substrate Integrated Waveguide Transition and In-phase Power Divider
Bibliographic record
Abstract
In this paper, a novel microstrip-to-FSIW (folded substrate integrated waveguide) is proposed, which has a lot of good performances such as low return loss and insertion loss from 6GHz to 13.8GHz. The field in FSIW has been studied before and is folded in H plane for TE10 mode. The field in the underneath substrate is similar to microstrip and the whole field in FSIW is similar to stripline so that the proposed transition can be realized by using stripline. In order to reduce the radiation loss, the stripline is shielded by two rows of conduct holes to constrain the field. What is more, an inductive metal via hole is positioned on the interface of stripline and FSIW to obtain better impedance matching in a broader bandwidth. There are some other types of transitions shown in this paper for comparison and an in-phase power divider is shown. The measured results are in good agreement with the simulated results.

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.
