Broadband half-mode substrate integrated waveguide (HMSIW) Wilkinson power divider
Bibliographic record
Abstract
A broadband H-plane Wilkinson power divider that makes use of the half-mode substrate integrated waveguide (HMSIW) technique is presented in this work for the first time. This broadband power divider utilizes the half-mode structure of SIWs such that the overall size is largely reduced at least by half. In addition, the lossy network or resistor branch is integrated with the SIW structure in order to obtain good output matching and isolation if unbalanced signals are combined or divided. The proposed concept is then validated by theoretical analysis and measurements. Good input return loss (S11) and insertion loss (S21, S31) performances are obtained theoretically and experimentally across a very broad bandwidth from 18 GHz up to 40 GHz. In the meanwhile, output return loss (S22, S33) and isolation (S23) better than −10 dB are also ensured across a 64% bandwidth from 18 GHz to 35 GHz.

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.
