Millimeter-Wave Broadband Circularly-Polarized Dielectric Resonator Antenna Array
Bibliographic record
Abstract
This paper proposes a broadband circularly-polarized (CP) sequential-fed dielectric resonator antenna (DRA) array for millimeter-wave (mm-wave) applications. The proposed antenna array has a wide 10-dB bandwidth of 4.36 GHz (24.89-29.25 GHz) and peak gain of more than 7.28 dBi within the operating band. The broadband response is achieved by placing a ring-shaped DRA over the cylindrical one. In this work, a sequential feeding network along with Z-shaped slots beneath the DRAs is used to achieve CP operation in a 2×2 array. It exhibits a 3-dB axial ratio bandwidth of 1.87 GHz (26.5-28.37 GHz). Moreover, it has a total efficiency and radiation efficiency of 80.14% and 95.83%, respectively. Due to its broadband operation range, wide 3-dB axial ratio bandwidth, high gain and efficiency, this antenna array is suitable choice for mm-wave wireless communication devices.

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.
