Abstract
A two-dimensionally scanning (2D) antenna array and polling beam scanning antenna array is designed in UHF RFID system with high stability and reliability in metal environment. The two-dimensionally scanning (2D) antenna array is composed of 3×3 antenna array, a feeding network and switches. The measured -10dB impedance bandwidth is around 30MHz. The scanning beam directions covers ±60° and scanning direction gain is 9~10dBi, respectively. The polling beam scanning antenna array is composed of three 1×2 planar inverted-F antenna (PIFA) arrays and polling beam scanning feeding network consisting switch and control module. The measured bandwidth is 50MHz (895-945MHz) under the condition of VSWR less than 2, covering Chinese, Canadian, Korean, and Australian standard of frequency ranges. The steering radiation pattern is -20°, 0°, and +25° in xoz-plane. The read rate achieve 100% in the metal environment.

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
