Abstract
Three different V‐band high gain printed log periodic dipole array (PLPDA) antenna prototypes are proposed. The antenna prototypes are fabricated and tested. A good agreement between the experimental and simulated results is obtained. Results show that those antenna prototypes can operate from 42 to 82 GHz with a fractional impedance bandwidth of 64.5% covering the whole V‐band (50–75 GHz). At 60 GHz, the three antenna prototypes have peak gain of 12.64, 23.31 and 26.79 dBi with a gain variation of 3.5 dBi across the whole V‐band with stable radiation patterns over the operating band. The proposed PLPDA antenna prototypes achieve good side‐lobe suppression, excellent front‐to‐back ratio in both E ‐ and H ‐planes and low cross‐polarisation levels over the entire frequency range.

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 it
