Abstract
This work presents a novel vertical sub-array intended for use in a C-band Multiple Input, Multiple Output (MIMO) radar. The 5-element sub-array, composed of proximity coupled split patch elements, is cost effective given that it uses only a single layer and is end-fed. The array uses a tapered amplitude distribution to reduce radar ground clutter caused by sidelobes. One of the challenges of an end-fed tapered array is that almost all of the input power must be transmitted through the weakest radiating element closest to the port. A proximity-coupled split patch antenna element is shown to be effective in obtaining both loose and tight coupling levels while providing a good match to the feed line. In the elevation plane, the optimized sub-array provides a measured maximum gain of 11.7 dBi at boresight, a half-power beamwidth of 16°, and sidelobe levels that are more than 15 dB down. To make the sub-array sufficiently compact to be tiled horizontally using a half-wavelength spacing, parts of the split patch elements are shared between neighboring sub-arrays. A 40-element two-dimensional receive array is designed using the proposed sub-array.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
