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.

How this classification was reachedexpand
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.
