Abstract
A novel antenna-filter-antenna-based asymmetric unit cell suitable for transmit-array (TA) is proposed in this letter. This unit cell converts a clockwise circular-polarized (CP) wave to counterclockwise CP with less than 0.5 dB insertion loss at 20.5 GHz, while its rotation provides up to 360° continuous phase shift in the transmitted wave. Hence, a 14 × 14 array of the proposed unit cell is fabricated and placed in front of a CP feed antenna. Placing the TA leads to a 9.5-dBi increase in the gain of the feed, and it redirects the beam to -15° off broadside. The axial ratio of the whole system is close to 2 dB. Therefore, this transmit-array can be used for fixed and/or steerable high-gain radiations for satellite communication in Ka-band.

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
