Multi-feed beam scanning circularly polarized Ka-Band reflectarray
Bibliographic record
Abstract
A multi-feed beam scanning circularly polarized (CP) reflectarray (RA) in the Ka-Band, has been presented in this paper. An A/4 unit cell with cross-bowtie element, have been used for the reflectarray design. The RA has an electrical size of 6.25A. A conical circular polarized feed horn is used to excite the RA. The multi-feed single reflector technique, has been used for beam scanning at certain angles. The focal distance in the feed phase center plane, is optimized to get good scanning performance from RA. This multi-feed mechanism can also be later used for different transmit and receiving band antennas, sharing the same reflectarray aperture. The proposed CP RA provides, 1-dB gain bandwidth of 32.8 %, 1.5 dB axial ratio bandwidth of 31 %, ±15° beam scanning off from broadside and the highest aperture efficiency of 47 %.

How this classification was reachedexpand
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.
