Bibliographic record
Abstract
Abstracts A rectangular patch antenna design with fundamental TM 100 mode for on‐metal applications is presented. The patch is excited by an inset‐fed microstrip feedline and optimized for better performance by varying the inset‐fed parameters. The patch is then loaded with a circular slot of radius R y at its center to create additional resonance at TM 11 mode. The radius R y is varied to elongate the circular slot into biconcave shape, to increase its electrical length. Thus, manipulating TM 11 mode with respect to TM 100 mode to achieve wideband by combining the two resonances using overlap technique. Equations of the resonance of the circular slot is stated and so is the surface area of the biconcave. The resulting antenna is etched on a 130 μm‐thick RO3003 microwave laminate and stamped on a metallic pipe cladding using the pipe as the metallic ground. The realized bandwidth is enhanced by 13% with reasonable achieved directivity. The simulated and measured results agreed reasonably with marginal discrepancy.

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.
