Abstract
An antenna system that combines reflectarray and conventional reflector technology is suggested for multi-band, multi-polarisation applications. This hybrid technology gives rise to the significant simplification of the feed system and relaxation of filtering requirements. The suggested design does not introduce additional volumetric requirements in comparison to equivalent conventional antenna systems. The proposed system is capable of maintaining mutually independent radiation patterns for each of its operating bands. A prototype that consists of a conventional ku-band offset reflector and a ka-band reflectarray was designed, fabricated, and tested. Close to 60% and 40% aperture efficiencies were realised in the lower and upper bands, respectively. The design procedure and experimental results are presented.

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
