Abstract
An integrated four-element dielectric resonator-based multiple-input-multiple-output (MIMO) polarization diversity antenna is proposed in this letter. The MIMO antenna comprises two microstrip-slot fed dielectric resonator antenna (DRA) elements and two conformal open-loop fed DRA elements. These two different types of antenna elements are intended to radiate in two opposite directions to reduce the field components' interference. This aspect can offer a reliable wireless connection. Also, circular polarization diversity is implemented between the diagonally placed antenna elements to improve the isolation and diversity performance. The measured overlapping impedance bandwidth (S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ii</sub> <; -10 dB) of 500 MHz (3.22-3.72 GHz) is attained for the proposed MIMO antenna with interport isolations of more than 15 dB throughout the usable frequency band. The proposed MIMO antenna acquires a measured overlapping axial ratio (AR) bandwidth (AR <; 3 dB) of 200 MHz (3.34-3.54 GHz), which covers the 3.4 GHz carrier frequency for the vehicle-to-vehicle and vehicle-to-infrastructure applications.

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
