60 GHz Substrate Integrated Waveguide-Fed Monolithic Grid Dielectric Resonator Antenna Arrays
Bibliographic record
Abstract
Artificial grid dielectric resonator antenna (GDRA) arrays integrated with longitudinal slot-fed substrate integrated waveguide networks are demonstrated at V-band for wideband and high-gain applications. The effective permittivity of a 500 μm thick, low-permittivity polymethyl methacrylate substrate is locally increased by a factor of 22.4 by embedding groups of micro-sized rectangular metal inclusions, each group functioning as antenna elements and collectively functioning as an antenna array. The monolithic GDRA array mitigates the problem of individual element misalignment over the feed slots while providing precise interelement spacing. GDRA prototypes with 4 × 4 and 8 × 8 array elements fabricated and tested at 60 GHz demonstrate a -10 dB impedance bandwidth of 10.4% and 12.0% with broadside peak realized gain of 15.2 and 19.4 dBi.

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.
