Millimeter-Wave Planar Antenna Array for Radar and Sensing Applications
Bibliographic record
Abstract
We propose an efficient high gain millimeter-wave planar antenna array. The packaging of the antenna array feeding structure is eliminated by aggregating the feeding network in between the antenna elements, which has a significant advantage in maintaining neat and symmetric radiation characteristics with low cross polarization level. The proposed antenna array is extremely low in cost and can be used as either a linearly or circularly polarized antenna array. The antenna array has a realized gain of 20 dBi in both scenarios. The matching bandwidth is 4.1 % and the 3-dB axial ratio bandwidth is 6%. The antenna array only uses a single substrate layer with no need for any vias. To switch to circular polarization operation, a 3D printed dielectric polarizer is used. The proposed antenna array suits well various applications at 24 GHz, while maintaining high performance metrics, and extremely low cost. The antenna array can be easily integrated with transceivers due to the use of printed microstrip line technology.

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.
