Compact UWB bandpass filter based on simple radial stub resonator structure
Bibliographic record
Abstract
In this letter, a new compact microstrip ultra-wideband (UWB) bandpass filter (BPF) is proposed. Using a new electrical model leading to a simple structure based on radial stub resonator (RSR), its originality resides in its noteworthy simple design approach where the filter response can be accurately adjusted by tuning three parameters only. The fabricated filter shows a good agreement between simulations and measurements whereas fulfilling UWB requirements, i.e., enhanced selectivity, good matching and flatness within the entire band of operation, and sufficiently constant group delay. With an overall size of 9.53 mm x 8.28 mm, a high compactness has been achieved, making this structure one of the most compact filters ever reported. © 2016 Wiley Periodicals, Inc.

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.
