Abstract
Abstract This work presents a compact wideband four-port Multiple-Input Multiple-Output (MIMO) Dielectric Resonator Antenna (DRA) for 5G applications in the millimeter-wave (mm-wave) band. The proposed MIMO structure comprises of four hexagonal dielectric resonator antennas (DRAs) mounted on a ground plane supported by a substrate, utilizing aperture-coupled microstrip feeding for excitation. Notches are incorporated at the center of the DRAs, enabling the excitation of multiple-resonant modes for achieving a wide bandwidth. Mutual coupling is reduced by employing a combination of isolation techniques, including polarization diversity, a defected ground structure (DGS), and metallic strips placed along the DRA sidewalls. The antenna operates over frequency band ranging between 22.99–30.49 GHz (28%) with maximum isolation greater than 33 dB. The achieved peak gain and radiation efficiency are 8.53 and 94.4% respectively. The design maintains a compact overall size of 1.60 λ o × 1.60 λ o × 0.20 λ o. The design approach is presented, emphasizing the effectiveness of the implemented isolation techniques. A prototype is developed and tested, demonstrating results that closely align with the simulations. The proposed MIMO antenna exhibits wideband operation, high isolation, and compactness, making it a promising candidate for modern 5G mm-wave MIMO systems.

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
