Wilkinson Power Divider With Fixed Width Substrate-Integrated Waveguide Line and a Distributed Isolation Resistance
Bibliographic record
Abstract
This letter proposes a new modified architecture of the Wilkinson power divider (WPD) based on fixed-width substrate-integrated waveguides (SIW) lines with optimal network isolation resistors. To overcome the problem related impedance variation of the SIW line without altering other characteristics, a reference impedance is used in all parts of WPD. The length of branches is designed considering this constraint. The isolation resistance is formed of n surface-mounted parallel resistors to reduce considerably the SIW-resistance discontinuity effect. The optimal number n of resistors depends on the package of the used surface-mounted resistor and thickness of the used substrate. The determined optimal number of resistances gives enhanced isolation performance over a wide frequency band. The results of measured manufactured prototype show 20-dB isolation bandwidth of 18% around 10 GHz. Compared with the previous designs, this new design offers smallest loss and broader bandwidth with simpler structure.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
