Template-Based Dielectric Resonator Antenna Arrays for Millimeter-Wave Applications
Bibliographic record
Abstract
An approach suitable for millimeter-wave dielectric resonator antenna (DRA) arrays is presented. The methodology involves fabricating precise cavities in acrylic templates and filling them with composite dielectric materials to create a monolithic polymer-based DRA (PRA) array layer. The excitation feed lines are fabricated on a separate substrate layer and the two layers are aligned and bonded together to form the PRA antenna array module. The impact of the acrylic frame on the PRA performance is analyzed through simulations. A four-element array operating at 60 GHz is realized to demonstrate the approach. The performance is characterized through simulation and also experimentally verified. The array offers a wide 12% impedance bandwidth at 60 GHz and broadside radiation with 10.5-dBi realized gain and stable radiation patterns. The use of polymer-based materials provides opportunities for cost-effective volume fabrication using molding techniques.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
