Abstract
Extensive research has been conducted on millimeter wave (mm-wave) chipset solutions led to reduction in size and cost while adding sensitivity and accuracy. Recent 79GHz chipset solutions using antenna-in package approach were developed for various applications with a wide beamwidth and low gain. However, for some applications such as multiple people vital signs detection and corridor gait monitoring, there is still a need to achieve higher gain with thinner beamwidth, to increase the signal-to-noise ratio (SNR) and the transmit/receive range of the system, mitigate the reflection from surrounding objects as well as reduce multi-path effects. The use of a lens is an appealing solution since it could improve the system performances while using existing chipset solution. Using low cost and rapid manufacturing 3D printing technology, we designed and fabricated a dielectric lens antenna for a 79GHz MIMO radar. Compared with the system without lens, the full-wave simulation demonstrated a 14dB improvement in gain which is in good agreement with measurement results.

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
