Open slot antenna in a small groundplane at the second resonance
Bibliographic record
Abstract
The open slot at second resonance in a small groundplane makes a simple, wideband antenna. The wider slot has a wider theoretical bandwidth as expected, but the best 50Ω impedance bandwidth calls for a given slot width. When the groundplane is small (<;λ2), the pattern retains a single lobe at each side of the groundplane with directivity over 6.2dBi. For a given slot width, the minimum groundplane size to retain the antenna 50Ω impedance performance is small, e.g., for the slot width w=0.06L=0.04λ (L=0.8λ), the required groundplane size is about 0.32λ by 0.83λ. The depth of the slot can range from 0.008/. to 0.167/. without significantly changing the performance.

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.
