Wideband, Beamsteerable Connected Slotted-Patch Antenna Array for On-Package Millimeter Wave Applications
Bibliographic record
Abstract
In this work, a long connected slot is cut out on a proximity-coupled patch antenna plane for the first time. The proposed connected slotted-patch antenna array (CSPAA) is designed, analyzed, fabricated, and measured for on-package millimeter-wave (mmWave) applications having wide beamsteering capabilities. Microstrip lines are used to excite the patch and the connected slot. The CSPAA is designed on a seven-layer vertical stack-up, making it suitable for on-package scenarios. The fabricated CSPAA has a measured bandwidth of 21.07% (centered at 28 GHz) and a measured realized gain of 9.51 dBi at broadside, yielding a total efficiency of 83%. The CSPAA demonstrates wide beamsteering capabilities up to ±390 with a compact form factor of 0.0881λ3 (1.52λ x 0.58λ x 0.1λ), where λ is the free-space wavelength at 28 GHz. A comprehensive comparison of the proposed CSPAA with the state-of-the-art shows that the proposed prototype has excellent bandwidth, gain, wide beamsteering capabilities, and a smaller form factor compared to previous solutions for mmWave on-package applications.

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.
