Abstract
This paper focuses on an engineered surface used in a novel compact antenna concept for multi-frequency Global Navigation Satellite Systems (GNSS) application and possibly L-band satellite communications. The antenna covers frequencies from 1.15 to 1.62 GHz and can be used as either a dual-band or wideband antenna. It is based on an annular ring dielectric resonator (DR) with a conformal cylindrical engineered surface inserted against the DR inner diameter. The antenna is excited using 4 ports fed in quadrature to maximize the circular polarization bandwidth and beamwidth. The engineered surface contributes to the antenna gain and impedance bandwidth enhancements and affects the undesired coupling between the feeding ports. It has been separately investigated to better understand its impact on the overall antenna performance. Some results of that study are provided in this paper.

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
