Control of bandstop response of cascaded microstrip low-pass-bandstop filters using arrowhead slots in backside metallic ground plane
Bibliographic record
Abstract
In this paper, a new equivalent circuit and modeling method for a uniform arrowhead-defected-ground-structure slot are proposed for the design of a DGS-cascade lowpass or bandstop filter. The effect of the geometry of a defected ground structure (DGS) on the performance of the cascaded-LPF or BSF and the effect of the cascaded-method is also examined. The proposed LPF or BSF based on pi-arrowhead DGS slot is 70% shorter than a conventional LPF. Only three cells of the proposed structure are necessary for a 15-dB stopband at 6 GHz. The validity of the proposed equivalent circuit model is established by comparing their response to the full-wave EM simulation of several structures. Measured results show that the new designs exhibit better performance by suppressing ripples and enlarging stopband bandwidth

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.
