A Novel Design of a Reconfigurable Bandpass Filter in Planar Technology for RF Applications
Bibliographic record
Abstract
This work presents a new design and study of a reconfigurable bandpass filter. The proposed structure is based on four square ring resonators etched on the top side of an RO4003C substrate, which has a permittivity of 3.55 and a loss tangent of 0.0021. The overall dimensions of the circuit are W = 17.67 mm and L = 17.67 mm. The final design incorporates a single layer containing four resonators. This filter was validated using two electromagnetic solvers, ADS and CST Microwave Studio (CST-MW). The design includes nine tunable capacitances, which were adjusted to achieve reconfigurability. The simulation results confirm the adequate performance of the bandpass filter and demonstrate its suitability for RF applications. The reconfigurability of the filter allows for flexible tuning of the frequency band, making it an ideal candidate for advanced communication systems requiring adaptive filtering across multiple frequency bands

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.
