Abstract
The synthesis and design approach for optimum reflectarray antenna feeds is introduced to maximize the obtained aperture efficiency. Feed antennas' radiation patterns are synthesized to uniformly illuminate reflectarray apertures for both center- and offset-feeding configurations using an inverse problem approach. Moreover, circular horn antennas with coaxial cavities are designed, fabricated, and measured to realize the required radiation characteristics covering the satellite communication band X-Ku (10.7-12.7 GHz). Theoretical analysis of the proposed optimum radiation pattern and realization designs are presented in comparison to a conventional conical horn feed showing a potential enhancement of the aperture efficiency. Furthermore, full-wave analysis is used to compute the radiation patterns, frequency responses of the aperture efficiency, and beam squints for the proposed realization feed antennas.

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
