Abstract
This paper proposes a novel dual-layer electromagnetic bandgap slotted circularly polarized patch antenna to design an 8x8 antenna array for massive MIMO operating at 3.5GHz. The antenna element structure achieves a bandwidth of 250 MHz (7.1% at 3.5GHz). It has a gain of 5.1dB, a directivity of 6.1dB, and a 3dB-beamwidth of 94 degrees. With EBG elements underneath, the radiating patch size can be reduced by 65% while the top EBG layer provides a high surface impedance and an isolation of 14.3dB between radiating patches with a separation distance of 0.32 wavelength. Simulation and measured results of the designed 8x8 antenna array on return loss, radiation patterns, mutual coupling, and beamforming performance in different scenarios are discussed and shown to be in good agreement.

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
