Advanced Spoof Surface Plasmon Polaritons based Wide Angle Broadband Dual-Beam Scanning Leaky-wave Antenna for sub-6 GHz Applications
Bibliographic record
Abstract
This work presents a new idea of planar single layer spoof surface plasmon polaritons transmission line (SSPP-TL) based wide angle dual-beam scanning antenna for sub-6GHz applications. A unique kind of groundless single layered (S-L) SSPP-TL is proposed using binary tree shape metallic grooves. This unique pattern on the substrate generates propagating slow-wave mode in the desired frequency range. For generation of the radiating fast-mode, hexagonal patches are arranged periodically in the close proximity of the metallic groove to achieve fast beam steering with complete elimination of open stopband (OSB) effect. The calculated and numerically simulated results show that the dual-beam steering of 326° (from ± 85° to ± 78°) is achieved in visible space while frequency sweeps from 3.92 GHz to 7.58 GHz in the sub-6 GHz band with maximum gain of 14.92 dB. The fractional bandwidth of 141.35 % is achieved for the proposed designed antenna.

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.
