Compact microstrip stepped‐impedance resonator (SIR) using localized substrate integrated artificial dielectric (L‐SIAD)
Bibliographic record
Abstract
Abstract This article presents a stepped‐impedance resonator (SIR) using microstrip line on localized substrate integrated artificial dielectric (L‐SIAD) structure. In L‐SIAD, the metal posts are periodically embedded in the lower substrate right under the microstrip line and connected to the ground plane, which results in the increasing of the effective permittivity and reduction of the SIR size, especially in the length of the SIR. The resonant frequencies of this SIR are analyzed for different post diameter, post height, and post period. Furthermore, the electromagnetic bandgap property due to the periodical posts is also studied, especially the influences on the resonant frequencies of the SIR. In final, this SIR is used to design an ultra‐wideband bandpass filter and the measured results demonstrated that the filter has broad upper stopband, low insertion loss in passband, and compact size. © 2012 Wiley Periodicals, Inc.

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.
