Abstract
Simultaneous improvement of matching and isolation for a modified two-element microstrip patch antenna array is proposed. Two simple patch antennas in a linear array structure are designed, whereas the impedance matching and isolation are improved without using any conventional matching networks. The presented low-profile multifunctional vialess structure comprises only two narrow T-shaped stubs connected to feedlines, a narrow rectangular stub between them, and a narrow rectangular slot on the ground plane. This design provides a simple, compact structure with low mutual coupling, low cost, and no adverse effects on the radiation and resonance. To validate the design, a compact, very closely spaced antenna array prototype is fabricated at 5.5 GHz that is suitable for multiple-input-multiple-output systems. The measured and simulated results are in good agreement with 16 and 40 dB of improvements in the matching and isolation, respectively.

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
