Single‐layer partially reflective surface for an orthogonally‐polarised dual‐band high‐gain resonant cavity antenna
Bibliographic record
Abstract
This study presents a novel dual‐band resonant cavity antenna (RCA) with orthogonal linear polarisations. The proposed RCA utilises one single‐sided slotted‐patch partially reflective surface (PRS) excited by a microstrip patch antenna. The two operating frequencies can be arbitrarily and independently controlled and the polarisation of each band is orthogonal to the other. A prototype is designed, fabricated and tested. The measured results show a dual broad‐side beam with lower‐band gain of 18.06 dBi at 10.25 GHz with vertical polarisation (V‐pol) and the upper‐band gain of 19.41 dBi at 11.05 GHz with horizontal polarisation (H‐pol). Besides, the proposed RCA has the capability of independent beam‐forming. By applying progressive phase gradient using variable slot length over PRS, the V‐pol lower‐band beam is tilted off broadside up to 29°, whereas the H‐pol upper‐band beam is fixed at broadside.

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.
