Substrate integrated waveguide dual‐stopband filter
Bibliographic record
Abstract
ABSTRACT A dual‐stopband filter in substrate integrated waveguide (SIW) technology is presented. The filter uses a uniform SIW transmission line loaded by three quarter‐wavelength H ‐plane stubs spaced by quarter‐wavelength sections. The two stopbands contain three transmission zeros (TZs) each and are located at center frequencies of 10 and 12.2 GHz with corresponding bandwidths of 360 and 500 MHz, respectively. The center frequency and bandwidth of the passband, separating the two stopbands, are 11.03 and 1.26 GHz. A capacitive post is used to improve the return loss of this passband and the location of its reflection zeros (RZs). The filter is prototyped and measured, and good agreement between measured and simulated results is obtained. The measured results confirm the predictions in terms of locations of TZs and RZs as well as passband return loss and stopband attenuation levels. © 2014 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.
