Triple Bandstop 2.5D Frequency Selective Surface for Sub-6 GHz 5G Communication
Bibliographic record
Abstract
The design of a miniaturized triple bandstop frequency selective surface (FSS) is presented for 5th generation (5G) communication systems. Meander lines in a spiral shape have been etched on the top and bottom of a dielectric substrate. To increase the electrical length of the FSS, the spirals are interconnected using four vias at the edges. The proposed design with a 5.2 × 5.2 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> footprint exhibits a triple bandstop response at sub-6 GHz frequency bands NR n46, LTE 42/LTE43, and LTE 46. The design is simple and cost-effective. As a miniaturized structure with rotational symmetry, it manifests polarization-independent characteristics with a stable frequency response for normal and oblique incident angles up to 84° (simulated) and 60° (measured). The transmission characteristics are verified using simulation and experiments. The proposed design can be used to shield 5G operational devices.

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.
