Abstract
Abstract An exponential tapered post‐wall slotline antenna loaded with dielectric lens is proposed and demonstrated. The theoretical profile of the loaded dielectric lens is derived, and its physical explanation is presented. Besides, the proposed post‐wall structure in the antenna ensures low available characteristic impedance as well as low cross‐polarization levels of the antenna. The proposed antenna exhibits an 18.12 GHz impedance bandwidth between 1.88 and 20 GHz and a peak gain of 10.9 dBi. The measured E‐plane and H‐plane cross‐polarization level is −37.0 and − 26.0 dB in boresight direction, respectively. Compared to the antenna without dielectric lens, the average gain of the proposed antenna increases by 3 dB from 14 to 20 GHz, and the pulse peak‐peak gain increases by 1.59 dB, and the tailing signal levels is about 0.35 dB lower.

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.
