A novel antenna configuration for millimeter wave communication systems
Bibliographic record
Abstract
This paper introduces a new way of building a cross-slot coupling patch antenna to generate dual polarization with a CPW feed line on a single layer for the EHF band around a center frequency of 38 GHz. The antenna structure developed combines the advantages of a CPW (coplanar waveguide) with the advantages of an aperture-coupled microstrip antenna, and simplifies the structure of the antenna by reducing the number of the metallization level, from 3 down to 2, thereby making easier the integration of the active devices. In addition, this type of coupling is advantageous when applied to millimeter wave monolithic phased arrays. A unique feed design eliminates the competition for surface space between the antenna elements and the feed network. In addition, the ground plane shields the antenna half-space from spurious radiation emitted by feed lines and active devices. The antenna is designed on a high dielectric constant substrate (/spl epsiv/r=9.9), which is close to the dielectric constant of GaAs and demonstrates the feasibility of integration of such an antenna structure into monolithic circuits.

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.
