Miniaturized Slotted Bandpass Filter Design Using a Ridged Half-Mode Substrate Integrated Waveguide
Bibliographic record
Abstract
This letter demonstrates significant miniaturization of slotted half-mode substrate integrated waveguide filters by incorporating a capacitive ridge. Based on this concept, two-pole and four-pole slotted bandpass filters are designed, fabricated and measured. Simulations are carried out using HFSS, and the prototypes are fabricated using a multi-layer printed circuit board process. The filters operate at 5.1 and 5.5 GHz and have a total width as small as 5.2 mm. The measured S-parameters of the slotted filters illustrate insertion loss of 0.8 dB and stopbands larger than 8 GHz. Compared to previously reported slotted half-mode substrate integrated waveguide filters, the proposed structure has a smaller footprint, lower insertion loss, and a larger stopband all at once.

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.
